Hey @peter-kal!
If you check the dbus interface doc, you can see:
a snap declaration is needed for your snap to be delivered via the snap store and claim this well-known DBus name (simply upload the snap to the store and request a manual review and a reviewer will take a look)
As you probably noticed, the declaration was granted for passie. If there is any further change in the well known name, the corresponding revision will fail again and this needs to be updated. There is no need to create a topic for this request, but feel free to do so if you want.
