In the User Profile page, you can:

a. Edit/add permissions as needed.
b. Deactivate active users / Activate blocked users. In case the user hasn’t yet accepted the invitation, it will have the option Resend Invitation.

Note! If you want to remove assigned permissions and/or want to add new permissions to a user, you should first add the new permissions and after – remove the permissions you want to remove. Otherwise, the user must be invited again as a new user.
