Hello beautiful xfce maintainers - I'm having an issue that is well described in this AskUbuntu question - [How to block Snap update notifications on XFCE?](https://askubuntu.com/questions/1425277/how-to-block-snap-update-notifications-on-xfce). Basically, `io.snapcraft.SessionAgent` is able to send pesky update notifications regardless of the Notifications filter rule, as well as if Do Not Disturb is on. How to test: * Install the Firefox Snap package * Filter io.snapcraft.SessionAgent from sending notifs, or enter do not disturb * Wait for a Firefox update * Get the notification If this is a bug in Snapcraft, let me know and I'll recreate the issue there. Thanks!
