Retrieving data by id from the card listed with Recyclerview

Question

I post an ad in my app. I pull the ads as a list from the firebase and list them with the recycler adapter. Using ViewModel. In each ad, there is the ID of the person who published the ad. My problem; I want to show the information about the advertiser in the card, but I could not find how to extract the data with the advertiser's ID in the adapter and connect it to each card. How should I go about this? I thought about transferring all users along with my ad list to the adapter and finding them from there, but it doesn't seem to be the right method.

I found a solution to the problem. I access my repository in Adapter as follows;

    val repo: FirebaseRepoInterFace

    @EntryPoint
    @InstallIn(SingletonComponent::class)
    interface RepoEntryPoint {
        fun getRepo(): FirebaseRepoInterFace
    }

    init {
        val repoEntryPoint =
            EntryPointAccessors.fromApplication(context, RepoEntryPoint::class.java)
        repo = repoEntryPoint.getRepo()
    }

Then, with the method in my repository, I bring the different users with their ids for each card.

override fun onBindViewHolder(holder: ViewHolder, position: Int) {
        post.userId?.let { id ->
            repo.getUserDataByDocumentId(id).addOnSuccessListener {
                holder.binding.user = it.toObject(UserModel::class.java)
            }
        }
}
