Won't allow notification access for KDE connect.
Just an FYI this is a terrible way to construct a post and request help, however this may assist you:
Go to the 'App Info' pane for the app in question, open the menu, and then press “Allow restricted settings” to unblock access to the app’s accessibility service.
This is an Android 13 feature which prevents "sideloaded" apps (those not installed via a session-based package installer) from using the accessibility and notification listener APIs without the user going out of their way to enable them. You'll encounter this issue with apps installed manually from APKs and from F-Droid because the latter doesn't use the modern package management API.
