Nextcloud Chat App + Fotos + Android client?


We are running the current version v14, and are looking for a group-chat app.
But “Talk” seems to be very minimalistic. Its Android-client does not even have the feature to send pics / fotos.

Is there any Alternative to Talk, that has an Android client that can send Fotos in group chats?
Video calls or voice is not needed.

Thx in advance,
