WebRTC Remote Assistant

[mia xara]

Hello I'm trying to make WebRTC Remote assistance like Agora Remote Assistant and vuforia chalk.

I'm using Unity ARFoundation and WebRTC Video Chat from asset store.

I have made the video call pc(Expert) to android(client) and share together AR.

When the client touch the touchscreen displays to the Expert the AR marker on his pc Screen.

My problem is I can't make when the Expert clicks with the mouse on the pc Screen to show to the client an AR marker to his Android phone.

I appreciate any help

Thanks
