Can we send private message in Microsoft Teams using bot on behalf of user in Teams ?

[jayantarijal]

We can send private messages from a Microsoft Bot to a Teams user. It appears as a chat between bot and a user.

But I need a functionality where a bot can send message on behalf of user in Teams and it would exactly appears as a 1:1 chat of two users in Teams, not as a chat between bot and a user.
