Hi @Lukas Babinger , You can use proactive messaging bot in Teams in this case. It will help you to trigger notification on your event to the user. You can follow the detailed documentation here.
The article provided by @Sharon Zhao-MSFT also has the details.
Along with this documentation, we have Proactive Bot Samples which you can check out from here

Hi,
is there any way to send a notification to a custom app in Microsoft Teams even if the app is not opened?
I created a PowerApp and integrated it into Teams. What I want to do now, is to send a notification (with this litte "1" on the app Icon) to all users with this app.
This should happen every time I update the contents of the PowerApp (of if I press any button or something).
How can I trigger notifications inside Teams?
Thanks!
BR
