# Generic config sets only `url`; the OAuth connect flow additionally needs the
# admin keys oauth_instance_url/client_id/client_secret, which only exist once an
# OAuth app is registered on Mattermost. This hook provisions that app on the
# partner and wires the returned credentials into Nextcloud.
