Hi there, I'm running KDE Connect on an Android 11 phone and Windows 11 PC.
My issue specifically is that the apps list that allows configuring which apps to enable/disable for the Notifications sync plugin is incomplete, so I can't filter out some apps.

For example, an app called Zoho Mail will forward its notifications to my Windows PC just fine, under the name of com.zoho.mail (another oddity is that it displays as its actual package name instead of the app name), but I can't find either com.zoho.mail or Zoho Mail from the KDE Connect Android app to disable.

I second that! I love KDE Connect and it's GSConnect gnome brother, but I can't exclude my lyric app from spamming me notifications on desktop when Connect automatically sends my youtube videos to my phone, which I can't disable either, although the latter might be an issue with GSConnect, not sure.
