[SOLVED] Oculus Private App on Quest Store without Publishing it + Cover Landscape image

If somebody needs a guide on how to publish a private app like if it was published, the steps are quite simple.

If you need a private application without the need to re-distrubute your App to the public but just for an internal usage, then

Fill up the forms on the https://developer.oculus.com/ like if you were publishing your app. But instead of Submiting for Review you click Save as Draft.

If you want your Store Images uploaded on your private Quest application, go to the Assets category (see image below) and upload all the images required. All of them + Screenshots and trailer, otherwise it won't load up.

P.S. Of course you need to sign your app otherwise it will appear in the unknown sources
