To change a user’s role, Admins can go to Settings > Workspace Settings > Members.
In the Members list, look up the user you want to change the role for and click on Edit > Edit Role.
There you can change the person's role and click save changes.
Pro tip: Only the Primary contact has the rights to manage Admin users. To add or remove a user as an Admin, please reach out to the Primary contact of your workspace. You can find out who it is in Settings > Members.
