Showing a default canned video upon initiation of video call

Hello everyone!
Could I check whether it is feasible / possible that in a video call, we default the caller to see the video of an avatar, instead of the other person? Something like the image I have posted below.

We are working for a call centre client. They would like the incoming caller to see the video of a 3D avatar, instead of the call agent.
On the other hand, the call agent should see the face of the incoming caller.
Thank you!

If the call agent has a virtual camera with this 3D output, yes it’s possible without updating any Jitsi code

Thanks for the answer, Emrah!
