+> Note, for `notifier.mattermost.bot` to work override, you must ensure you enable application/ webhook overrides on your Mattermost system. If you do not, the webhook will, by default, take the name of its creator. If you cannot enable application/ webhook overrides, you might have to consider creating a dedicated `tfnotify` Mattermost user account.
