How to set cursor size for a pointable canvas? Meta XR Interaction SDK

I am experimenting with VR UI using the Meta Interaction SDK samples. After creating a Pointable Canvas and placing it 0.5m in front, as shown in the attached image, the pointer becomes too large and obscures the UI. I have looked through the components, but I cannot figure out how to appropriately adjust the pointer size. If anyone knows, I would appreciate your guidance.
