Tying to load WebXR page without arcore

I am trying to load an example webxr page WebXR_AR_Cones
Unfortunately my Samsung galaxy a6+ (sm-a605g) does not support arcore. I’ve checked it from the following image.
I’ve also encountered a github post related to this.
So I want to try an alternative like plugXR . But unfortunately it is crashing.
Some people are pointing at poor gyroscope calibration in the above github thread.But I found some android apps with ar capabilities that runs without arcore in my device. Is there any way to test webXR on my phone (sm-a605g)? By any means?

According to the following guide, you can only use WebXR on Android if ARCore is installed.
