User Privileges: 

If the user is unable to change the item quantity or unable to recall the order then we have to give rights to a user from the admin user in Optimus Back.

In the above screenshot, we can see the privileges.

IF you are looking to see the privilege for Edit function then edit the user and below privileges, there is empty space where we can write edit, So all the edit right will show to us and we can select those rights and click on edit.

Note: once we changed in the backed under the user then please ask the user to re-login and try.
