In theory it should work, because the plugin uses the Gamepad API from Javascript, which can get the haptic actuators from your connected gamepad. This means, the API should find your oculus quest 2 controllers and their actuators for the vibration/rumble function.

Here you can look at the API in detail. It also mentions controllers similar to the oculus quest 2.
When you try my plugin, you can write me, if it works.
