Is your feature request related to a problem? Please describe.
I feel like Gotify is missing a key feature, there’s no way to have shared apps that multiple users can use. Gotify is great for notifications, but it falls short if you can’t send notifications to groups or share apps between users. That makes it hard to use for groups or households.

Describe the solution you'd like
I’d love to see support for shared apps that can be accessed by multiple users. One way to do this would be if notifications posted to one app could be forwarded to other apps/users. This forwarding should be locked down and only configurable by administrators to avoid misuse.

This would let a single app send notifications to a group of people instead of just one user. Group and personal notifications combined would make Gotify way more useful for households or group setups.

I personally use Gotify for Home Assistant and smart home notifications, but to cover my entire family, I’d have to create an app for each person, get a token for each, then create a script for each app in Home Assistant. Being able to forward notifications from one app to others, or mark an app as a shared channel and pick which users get those notifications — BAM, done.

Describe alternatives you've considered
Right now, I have to create separate apps for each user or rely on individual notifications, which is clunky and not scalable for groups. I’ve tried NTFY, NOVU, Rocket.Chat, and a few other smaller projects. Even dabbled with MQTT. But nothing matches how reliable and no-nonsense Gotify is.

Additional context
Gotify is awesome overall — this forwarding or shared group feature feels like an essential next step and a total game changer. There’s no real solution out there that checks all the boxes like Gotify does. Would love to see this in a future update!
