Depends on the actual NEED. There are 3-4 common paths that we see: 1. Remove the NEED, maybe it wasn't that important anyway 2. Replace Google Push with #UnifiedPush 3. Replace Play Services with #microG 4. Replace the camera/QR lib with a FOSS one.

all you need to do is implement #unifiedpush like all the other foss apps needing push.

I have one background connection for mastodon/signal/telegram/findmydevice/matrix,davx5..... and a second for deltachat. 🙄

to bring push notification also to the fdroid installations #chatmail server should support #unifiedpush.
