Nextcloud integration - iOS App Nextcloud Button missing


I’m relatively new to Rocke.Chat and while I managed to integrate Rocket.Chat via Oauth2 with our Nextcloud, I’m not able to sign in using my Nextcloud credentials in the iOS app, because there is no Nextcloud button.

What am I doing wrong!? :thinking:

Thank you for your help in advance,

Or maybe to say it in other words: How do I sign in using the iOS-App with my Nextcloud-Account? Is it possible at all like it is in a browser?


Anybody? :slight_smile:
I’m wonderung what’s wrong with my question?
