Asgards Wrath 2 is 35GB on my Quest 3 but when I back up the APK in Sidequest it's only 88MB?? Is that the entire app backed up? If so what is taking all the extra space? Or can't Sidequest back up that game properly?

It took forever to download it so I want to use the APK restore instead if I decide to delete it temporarily to create enough space on my Quest 3 128GB. Meta should have released a 256GB version if they are going to have massive game downloads like this one.
