Requires your Forgejo instance admin to enable CORS for at least the
origin which serves the notification panel. Please see
[here](https://forgejo.org/docs/latest/admin/config-cheat-sheet/#cors-cors)
for more information.

NOTE: The test [forgejo configuration](./integration/conf/app.ini) may
be insecure for your usecase since it allows CORS for all origins with
the widest possible surface.
