Conversations involving multiple participants, allowing collaboration and information sharing in Teams
Hi, Krishna. I am an independent advisor, trying to help other users in the Community with my experience in Microsoft products. Please note that I am a user like you and don't work directly for Microsoft.
Unfortunately, this feature is unavailable on teams for now. You need an internet connection to use the full functionality of Teams.
I also recommend providing feedback directly to Microsoft Teams through the feedback portal https://feedbackportal.microsoft.com/feedback so that they can add this to future releases.
I hope this helps you. Let me know if this contradicts what you need. I remain helpful in answering any more of your questions.
Warm Regards
Femi
