Hi @Neha Pingale - We tried to repro this issue by starting a chat & placing a call using deep link in New Teams and observed that the chat is getting opened within Desktop client itself, so does the call.
Deep link Used:
For Chat: https://teams.microsoft.com/l/chat/0/0?users=<user1>
For Call: https://teams.microsoft.com/l/call/0/0?users=<user1>
Thanks,
Prasad Das
