Guessing you've figured out you can use Sidequest to open and sideload apks from your computer folder (IOW that aren't available in the SideQuest Browser, itself) into the Quest.
Right, but that wasn't the overall point, which is that literally one or two extra steps clearly hasn't killed you, and it's also good for incoming noobs to know they can/learn how to use SideQuest to sideload apks that aren't on SideQuest.
Actually, a better point is that this app runs terribly on Quest and shouldn't even be bothered with.
