Click the Admin section on the left-side menu. Here, you can see a list of admins, among whom the first one is the person that created the workspace.
You can add a new admin by clicking +New Admin. When you click +New Admin, a form will pop up. The Add a New Admin process has 2 steps.
First, you should enter a User ID that already exists in your workspace. If you haven’t added the intended user yet, please refer to the instructions on how to add a single user (link to the instructions).
After adding a User ID, the next step is specifying their Additional Permission. By default, the new administrator will not be able to perform any operation. Select the necessary permissions for the new administrator and Check the box to select all the options (equivalent to the owner’s permissions).
