How to send haptic feedback on UI hover/tap in Jetpack compose?

Hi, I am looking for a way to send small vibration as a haptic feedback on my 2D panel app whenever user hovers their raycast over a UI element, and stronger vibration when they tap on that element. ...

    Hi! You can do this with the SpatialInterface.applyHapticFeedback() function.

    // inside your AppSystemActivity somewhere
// "spatial" is a SpatialInterface inherited from VrActivity
// you can pass it around to somewhere else you need it reference it
spatial.applyHapticFeedback(
   // hand: Apply haptics to the specified controller hand.
   Hand.RIGHT,
   // amplitude: Value between 0 - 1 for strength of haptics.
   0.3f,
   // duration: Time in nanoseconds for how long the haptic feedback should be applied.
   (0.03 * 1e9).toLong(),
   // frequency`: Frequency of vibration (in hz).
   128f
)

    Hopefully this should help!
