You can add a tab or mention a record in a Teams Meeting as well, though I have not tested this out yet myself.
In my experience, I was not able to get the Mention feature to work in the regular Chat functionality of Teams – only the chat within a Team itself. You can add a Tab, however, though not sure what the use case would be for doing so.
Usability of these features are limited or not available on mobile, however, both the desktop and web version of Teams work.
If your organization uses Active Directory for Salesforce access, this will work fine. Though you have to type in your custom domain each time.
All in, expect to spend about an hour getting the initial setup configured. For user management, consider a guidebook on use cases, examples, and best practices for mentioning and adding records to channels. The biggest element to address is the security, privacy, and user access roles. Consider who has access to the Team, who has Salesforce licenses, and of those, who have permission for the integration.
