This was one of the surprise bonus features of using Android over IOS. Before they fixed their camera gallery to make the spheres work in the app, the download and stitching internally only made the flat pano that you could move and zoom with swiping. But Google photos automatically made a version that you can do the VR and even split for viewer.
(Side note that we are still fascinated by a 3D image through goggles like those early viewers at the turn of the previous century)
That made showing my images easy because I don’t need FF open at all post download of photos. The automatic file sharing Google photos has with the Android version of the app I find very useful and makes look great and as a photo pilot.
