Then scroll to the bottom to "Spend Bands"
Click the "edit" icon to the right of the spend band you would like to add or remove the user from. A drawer will slide out on the right hand side. Click "users"
Click Add user and search for the person you want to add
Click the user name, a green toast will appear in the top right showing confirmation. Click close and the action is completed. If you use department locking please re-lock the department.
