Question regarding installation of a codec

Hello,

we recently ported an app from quest to rift so it runs natively on PC, the main function of the app is to play 360 videos. The app needs a codec to play these videos properly. If I understand the oculus store guidelines we must not create an installation executable and upload that to the store, we need to upload the app in a zip file. What would be the best way to deliver this codec to the end users?
