ARCore Face Tracking on iOS for Face Masks

For a current project we are developing, we need AR Face Tracking that can work well while a person is wearing a face mask on iOS.

In ARFoundation, when building to iOS and using ARKit, face tracking is lost while the user is wearing a face covering. Experimenting with the ARCore XCode Face Tracking SDK, the face tracking while wearing a mask is very good on iOS!

We're looking for a solution that allows us to use the ARCore Face Tracker on iOS instead of ARKit's. Currently this has not seemed possible with ARFoundation (does not support ARCore on iOS I don't believe), ARCore_Unity_SDK (Face Tracking example does not build to iOS and the iOS sample ALSO uses ARKit).

Any ideas or solutions are greatly appreciated. ARCore's face tracking also supports much older iOS devices (does not require the TrueDepth camera) so I think this could be a good feature overall!

Thanks
