Is it possible to write an app to show a list of conversations by subject name

[alphabeta]

Is it possible to write an app that could show a list of conversations in a channel by subject with a link that would open just that conversation for viewing in a window by itself.

Well, this is something that depends on the Teams APIs but I don't see a reason why this could not be possible...you will need to explore Graph API (also the beta EndPoint) to check if all this information is provided so you can consume it in your custom app

Thanks.  Looks like it's in the beta but not in the current released API

Any idea how to find out when the beta will become current/ released?
