Invited users and requests (pending and disapproved) in the "Requests" tab can be edited in the "Edit invitation" and "Edit pending/disapproved request" dialog. In the respective dialog, you can see details about invitations/requests and make changes as needed. As a manager, you will find it easier to have an overview of all the settings directly in the dialog.
To edit:
Go to "Organisation members" page.
Click on the invitation/request in the "Requests"
tab. An "Edit" dialog opens.
In the dialog, you can:
See user's details.
See and manage their privileges (only for "Invited" users).
If the invited user rejects the invitation, any group membership and privileges they have will be revoked.
See and manage group membership via the "Add group members" icon (only for "Invited" users).
Imported groups are not shown as an option when adding members. For more info on imported groups, see "Imported groups considerations".
Click "Save" to apply any changes made.
