SearchView doesn't show recent query suggestions

Question

I'm learning Android development and trying to add recent query suggestions following official documentation: Link. When i launch the app, there are no suggestions at all. Search by itself is working just fine. My searchView is located in a toolbar, the whole app is made of single activity and fragment. I managed to do it using RecyclerView and SharedPreferences, but it looks not so elegant and pretty and requires refactoring of my old code. I've seen related question, but nothing really answers mine.

manifest.xml:

    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:name=".PhotoGalleryApplication"
        android:allowBackup="true"
        android:dataExtractionRules="@xml/data_extraction_rules"
        android:fullBackupContent="@xml/backup_rules"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.PhotoGallery"
        tools:targetApi="31">
        <provider
            android:name="com.vortex.android.photogallery.SuggestionProvider"
            android:authorities="com.vortex.android.photogallery.SuggestionProvider"
            android:exported="false"
            android:enabled="true" />
        <meta-data
            android:name="android.app.searchable"
            android:resource="@xml/searchable" />
        <activity
            android:name=".MainActivity"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <action android:name="android.intent.action.SEARCH" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

searchable.xml:

<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:label="@string/app_name"
    android:hint="TEST"
    android:searchSuggestAuthority="com.vortex.android.photogallery.SuggestionProvider"
    android:searchSuggestSelection=" ?">
</searchable>

SuggestionProvider.kt:

class SuggestionProvider: SearchRecentSuggestionsProvider() {

    init {
        setupSuggestions(AUTHORITY, MODE)
    }

    companion object {
        const val AUTHORITY = "com.vortex.android.photogallery.SuggestionProvider"
        const val MODE: Int = DATABASE_MODE_QUERIES
    }
}

My toolbar layout:

<menu
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <item android:id="@+id/menu_item_search"
        android:title="@string/search"
        app:actionViewClass="androidx.appcompat.widget.SearchView"
        app:showAsAction="ifRoom" />

    <item android:id="@+id/menu_item_clear"
        android:title="@string/clear_search"
        app:showAsAction="never" />
</menu>

Part of my code from Fragment class:

override fun onCreateMenu(menu: Menu, menuInflater: MenuInflater) {
        menuInflater.inflate (R.menu.fragment_photo_gallery, menu)

        val searchItem: MenuItem = menu.findItem(R.id.menu_item_search)
        searchView = searchItem.actionView as? SearchView
        val searchManager = requireContext().getSystemService(Context.SEARCH_SERVICE) as SearchManager

        searchView?.setSearchableInfo(searchManager.getSearchableInfo(activity?.componentName))

        searchView?.setOnQueryTextListener(object : SearchView.OnQueryTextListener {

            override fun onQueryTextSubmit(query: String?): Boolean {
                ...
                handleSearchQuery(query)
      
                if (query != photoGalleryViewModel.galleryItem.value.query) {
                    binding.progressBar.visibility = View.VISIBLE
                    binding.photoGrid.visibility = View.INVISIBLE

                    photoGalleryViewModel.setQuery(query ?: "")
                }
                return true
            }

            override fun onQueryTextChange(newText: String?): Boolean {
                return false
            }
        })
    }

private fun handleSearchQuery(query: String?) {
        query?.let {
            SearchRecentSuggestions(
                requireContext(),
                SuggestionProvider.AUTHORITY,
                SuggestionProvider.MODE
            ).saveRecentQuery(it, null)
        }
    }
