Saving Teams Channel Chats before removing the Team Replies

[Ofer-Gal]

I was able to drill down to the Get-PnPTeamsChannelMessage and found out I can get the content.
I found out there are replies associated with each message but there is no ".Replies" in the intellisense. is this not done yet? or did I miss something?

Also do I really need to save the posts before removing the group? are they saved somewhere else I can get to if I am asked to get out of an archive.
