Unsubscribe agents as an admin

Scenario:
Sometimes agents can be accidentally subscribed to not needed objects. We need a quick way to unsubscribe them without the need to impersonate (login as) each agent and unsubscribe them via mass edit from its user profile

Current workaround:
- navigate to user's profile and save its link
- click on "Login As" like on photo 1

- go to its user profile (use copied link)
- select all tickets you want to unsubscribe
- click unsubscribe like photo 2
