After testing our solutions with users, it turned out that they could not find our solution. First, they expect to find it in the application's settings, which is where the administrator can grant permissions. Secondly, as they already knew that it was not in the settings and in the request page view, they could not find it. The option with “view as” filter didn’t seem to be obvious, and the option with ‘View as’ under the user profile miniature was too much hidden.
