How to remove mobile app integration?

This is probably stupid but how do I uninstall this integration? I don’t have any “…”

EDIT: Now that I look at it, any integration that has a list does not have the ellipses.
Pihole, minecraft, mobile app, wled.

I don’t know if I should repost this in a different location but I just want to uninstall / reinstall to get my notifications working.

I had to manually delete each device then the integration itself.
