As an agent, you can edit user details that users see in their profile.
Users can see the following information:
Emails, job title, organization, organization website and time zone.
Agents see can that and a lot more:
Go to the People page in the Admin Panel and search for a desired user by name, email or organization.
Click on the ⋮ button on the right from a desired user and select Edit Profile.
Change desired details in the user profile and click Save.
Tip: Clicking a user avatar also usually opens the user profile page or user profile modal window.
Agents can also edit their own profiles in the same fashion.
