Physics X bug with trigger event?

[randdev]

I am using the Physics X as physics backend to build for native android and IOS, and i found out that if both rigidbodies with trigger collider attached, they wont generate trigger events like this document provide here. (it works for bullet physics)
https://docs.cocos.com/creator/manual/en/physics/physics-event.html

One collider must be non trigger for this to work.
@zhangxm Can you please check on this.

Note : The collision event between two triggers is not supported in the PhysX backend.

Can you please update the document for what PhysX differences compare to Bullet ? There are so many edge cases i found that make the switch between physics engine backend not as seamless and it should be.

There are notes on this part of the content in the document.
