As an admin user, even though you are able to change your own access level, it would be best to avoid experimenting with it. This is especially important if you own workflows. Changing your access level could lead to a miscommunication on the backend processes tied to your username.
Atlan recommends creating a member or guest login with a dedicated email address for each and using them for testing views and permissions. This will help you accomplish the same goal while avoiding potential disruptions and leaving your admin access intact.
