How to obtain, FoV values for eyes VisionOS

Hi,

We have been experimenting with VisionOS and we are in need to query the field of view values for each eye of the device. We are currently using drawable.views[0].tangents and drawable.views[1].tangents respectively which is labeled as 'Depreceated' . We wonder is there an alternative function for obrtaining FOVs since we had no luck to calcuate them out of the projection matrix we obtain from drawables.

Thanks
