Not able to view AR on Android devices where size of glb big

[NitinJ88]

Description

When I try to launch AR viewer in my application for big size glb ( >=3MB) then AR viewer does not pop-up on my Android device.
Looks like AR is loading in background and till that time browser time out the request.
I am getting following error on console:
"DOMException: Failed to execute 'requestSession' on 'XRSystem': The requested session requires user activation."

Are you trying to bypass our AR button? As the error says, XR requires user activation, so if it's not tied to a user click, the browser will block you, hence our button.
