Additional team and channel-related features and issues within Microsoft Teams for business
It works for me with Teams desktop version 24193.1804.3021.7765.
Also it says my client version is "Your client version is 49/24071128815".
Works also on Teams web.
Hope this helps

Thanks for the version post, looks like Microsoft is rolling this out slowly, I still have a version older and still don't have this feature.
