You can edit the role of a team member by going to Settings > Team Management.
Locate the team member to remove and click on the more menu (...).
From there, you can:
Disable access to the team. This is useful to temporarily suspend users (e.g., contractors) without fully removing them from the team. The user’s access can be reactivated at any time from the same menu.
Remove access to the team. Reactivating the user will require sending them a new invite (see Invite people to your team)
Disabled users can have their access reinstated by selecting Enable from the more menu (...).
