In a shared meeting room environment one of the recommended secure configurations is to force ephemeral browser profiles (Chrome/Edge Chromium). Using this policy, on every next startup Chrome browser creates a new profile that is automatically deleted on the next closure. In this scenario users' credentials, history, profile settings, and extensions are deleted.
Google Chrome provides an option to force install extensions for every new profile.
