Wait really?! I was wondering why I would want to fork over so much money for the app, but having this as a possibility changes everything. Thanks for the heads up :D
You may be interested in the alternative (official) solution, which is not wireless but allows streaming PC VR games using "Oculus Link" using a compatible USBC cable. The cable that comes in the box is unfortunately USB2.0 (so not compatible), your best bet is to checkout this page: https://support.oculus.com/444256562873335/. The official Oculus cable has fibre-optic transceivers built in so is very expensive. Oculus lists some third-party cables on Amazon by Anker, which used by a lot of people (10 foot recommended, but the tiny 3 foot one is really cheap).
I haven't yet tried Virtual Desktop 5GHz streaming, but Oculus Link with a 3 foot cable streams perfectly (good for seated VR, which many PC games assume). I do want to try 5GHz Wifi streaming though! Untethered play is the best!

Loading up the SideQuest APK was super easy and has now led me down the awesome rabbit hole of poking at Oculus dev :D
As mentioned, definitely make sure you're connected to the 5GHz hotspot if it's available -- it makes a big difference in my experience streaming a regular desktop with VirtualDesktop. Also as you might be aware, unlike regular 2.6GHz wifi, please remember that 5GHz signals don't penetrate objects (including walls, furniture) so your best bet to reduce potential lag (and thus nausea) is to make sure your Quest always line-of-sight to the router.
