Metion with "@" shows the the user itself.

After type "@", it shows the user self in the list. Is there a way to disable it?

Hi @zeroarst ,

You can achieve something like this by utilising the UserLookupHandler class which handles the user search logic when searching for users to mention. For example:

// Instantiate the default user handler that is used by the SDK
val delegate = DefaultUserLookupHandler(
    chatClient = ChatClient.instance(),
    channelCid = channelId,
)
// Create your own handler, which wraps the default one
val handler = UserLookupHandler { query ->
    // Use the default one to fetch the original results
    val defaultResults = delegate.handleUserLookup(query)
    // Filter the results, so that the current user is excluded from the results
    defaultResults.filter { it.id != ChatClient.instance().getCurrentUser()?.id }
}
// Pass the new UserLookupHandler to the ViewModelFactory
val viewModelFactory = MessagesViewModelFactory(
    context = this,
    channelId = channelId,
    userLookupHandler = handler,
    // other setup
)

Or you can do something similar, by providing a custom localFilter to the DefaultUserLookupHandler:

val delegateFilter: QueryFilter<User> = DefaultQueryFilter { it.name.ifBlank { it.id } }
val filter: QueryFilter<User> = QueryFilter { items, query ->
    delegateFilter
        .filter(items, query)
        .filter { it.id != ChatClient.instance().getCurrentUser()?.id }
}
val handler = DefaultUserLookupHandler(
    chatClient = ChatClient.instance(),
    channelCid = channelId,
    localFilter = filter,
)
MessagesViewModelFactory(
     context = this,
     channelId = channelId,
     userLookupHandler = handler,
     // Other setup
)

Note: This is a simple implementation based on the default handler + applying filter - you can also play around with your fully custom UserLookupHandler implementations.

Let me know if this will fit your use-case!

Best regards,
