Open AR screen with script without clicked button

[Azeem00786]

Hii there,
i want to open AR screen automatic on DOMContentLoaded for which i am using
document.addEventListener("DOMContentLoaded", function () { setTimeout(() => xrButton.__onXRButtonClick(), 2000); });
this is working fine on desktop browser but when i am testing the same thing in my phone browser it is not working. we are getting this error in console-
XRSession creation failed: Failed to execute 'requestSession' on 'XRSystem': The requested session requires user activation.

while on click button manually on same device with same browser it is working.

It is a mobile limitation that prevents full screen, camera access and things like that without user consent/click/activation
There are several discussions online about it and maybe some workarounds that i haven't explored

This should not work on desktop, which browser is it?
WebXR requires a user interaction with the page to start, this is an intentional restriction.
