Is there any chance Cloudron could get a companion app for self hosted self build Mattermost - https://developers.mattermost.com/contribute/mobile/push-notifications/service/ ?
It is required, if you build your own version of mobile apps.
If not or not in any near future, is there any Cloudron way to install it alongside with Mattermost?
@potemkin_ai Yes, this has to be packaged as a separate app (I think similar applies for rocket.chat). Thing is one has to compile and publish their own mobile apps. This is a lot of work (and also some $ investment since the app stores require some payment from publishers). You can open a thread in the App Wishlist in any case and we can see if there is interest.
