Hello,
There is not a direct way to enable bot in Team. But I have found some solutions and blogs which shows different scenario of Interactive Voice Response with bot, hope it helps.
Scenario 1: Bots can interact with Teams calls and meetings using real-time voice, video, and screen sharing.

Scenario 2: interactive voice response (IVR) application with a bot and custom machine-learning intelligence.
