Thank you for your patience. We are thrilled to that replying to a chat message in the desktop client is now available as part of our Public Preview. It is expected to roll out to the public ring over the next several weeks.
For details on switching to the Microsoft Teams Public Preview version, please see : https://aka.ms/TeamsPublicPreview.
We look forward to your preview feedback!

This is an absolutely necessary feature in order for my company to consider implementing Microsoft Teams over other team-based collaboration solutions... We realize that the pop out arrow button is already in place, but interacting with desktop alerts (Windows-native or In-App) for those chats always redirect improperly to the main Teams window rather than the popped-out chat windows.
