Using hosts camera while accessing client pc remotely via zoom remote access

Hi,

I am looking for help on a zoom remote access session where I need to use the host's camera while working on an application on a remotely access PC via zoom session.

USE CASE:

Consider 2 computers on a zoom session - A and B

A is the meeting host

B is the client connected to the meeting via an invite sent from A

A takes remote access control of B via zoom remote access feature.

A is working on an application on B that uses camera to scan some images.

When that application on B triggers the use of camera, it activates local camera on B by default.

How can I make it trigger the camera of the host PC (A) in this situation instead of using local camera on B?

OR

How do I setup zoom to let the host use its own camera instead of B during remote access sessions?

I know when using Remote Desktop softwares, this feature can be configured in them but not sure how / where to configure this requirement in zoom for zoom remote access feature.

Any help would be greatly appreciated.
