App Groups and macOS 15

Hi, I just updated my machine to macOS 15, and while developing and running my app (with Xcode), I keep getting messages about my app "would like to access data from other apps". This happens even from Xcode Previews, so it's pretty annoying. My production app doesn't seem to be affected by this problem; the system prompt just pops when running the debug version.

I came across something about App Groups in macOS and how something has changed in macOS15 regarding system permissions. I use the "group.***" prefix in my macOS app, without the team prefix. Is that the problem here? But why is my production app working fine, but the development app is triggering the prompt repeatedly?

Would love any feedback or workarounds. Thanks.
