MISSING!!! alpha in Hand Phone Gesture by underconstruct


I downloaded Hand Phone Gesture by (underconstruct - Envato Elements) and was wondering whether or not there is a missing alpha channel for the mobile phone element?
The other products by this author seem to have them and this makes it easy to apply a mask in FCP but this particular element is missing or there is a trick to extracting the alpha from the only movie there is of the iphone element?

thanks in advance
