3D Buttons interactive when invisible in Unity App for Oculus

Our team is working on implementing 3D buttons using PokeInteractable on a World Space Canvas that has Mask and RectMask2D components. 

The problem arises when the buttons are not visible due to the mask, as they still remain interactable. We are seeking guidance on how to ensure that the interactivity of the 3D buttons aligns with their visibility, specifically within the defined boundaries set by the Mask and RectMask2D components.
