To have an overview of expiring Personal|Group|Project Access Token a calendar view of upcoming expiry dates would be helpful. Exposing the expiry dates in iCalendar format would enable our users to import into their calendar tool of choice. With our [path-dependent feed token](https://gitlab.com/gitlab-org/gitlab/-/issues/414257) for `.ics` endpoints the `feed_token` in the iCalendar URL will not be usable for any other URL. Implementation tracking: - [x] [Personal Access Token](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/153093) available at https://gitlab.com/-/user_settings/personal_access_tokens.ics - [ ] Group Access Token - TBD - [ ] Project Access Token - TBD
