Intent(TelecomManager.ACTION_CHANGE_DEFAULT_DIALER) don't show dialog to set default dialer app

Question

I want my app to become default dialer, but when I'm trying to create dialog for user to set default app, my app is rejecting it itself (it's showing toast "User declined request to become default dialer) Testing on Samsung Galaxy S10+ My MainActivity.kt:

class MainActivity : BaseActivity() {
    companion object {
        private const val REQUEST_CODE_SET_DEFAULT_DIALER = 100
    }
    override val navigationGraphResId = R.navigation.nav_graph

    @RequiresApi(Build.VERSION_CODES.M)
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        checkDefaultDialer()
    }

    private fun checkDefaultDialer() {
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) return

        val telecomManager = getSystemService(TELECOM_SERVICE) as TelecomManager
        val isAlreadyDefaultDialer = packageName == telecomManager.defaultDialerPackage
        if (isAlreadyDefaultDialer) return

        val intent = Intent(TelecomManager.ACTION_CHANGE_DEFAULT_DIALER)
            .putExtra(TelecomManager.EXTRA_CHANGE_DEFAULT_DIALER_PACKAGE_NAME, packageName)

        startActivityForResult(intent, REQUEST_CODE_SET_DEFAULT_DIALER)
    }

    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
        when (requestCode) {
            REQUEST_CODE_SET_DEFAULT_DIALER -> checkSetDefaultDialerResult(resultCode)
        }
    }

    private fun checkSetDefaultDialerResult(resultCode: Int) {
        val message = when (resultCode) {
            RESULT_OK       -> "User accepted request to become default dialer"
            RESULT_CANCELED -> "User declined request to become default dialer"
            else            -> "Unexpected result code $resultCode"
        }

        Toast.makeText(this, message, Toast.LENGTH_SHORT).show()
    }

}

I placed intent-filter in AndroidManifest.xml:

 <activity
            android:name=".MainActivity"
            android:screenOrientation="portrait">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

            <intent-filter>
                <action android:name="android.intent.action.VIEW"/>
                <action android:name="android.intent.action.DIAL"/>

                <category android:name="android.intent.category.DEFAULT"/>
                <category android:name="android.intent.category.BROWSABLE"/>

                <data android:scheme="tel"/>
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.DIAL"/>

                <category android:name="android.intent.category.DEFAULT"/>
            </intent-filter>

        </activity>

Thanks for help
