Cant update applab metadata PDP video

Hello,

I have an app on applab, and i want to update the video shown on the PDP, but i cant figure out how to do it. I saw this page,

https://developer.oculus.com/resources/publish-content-updating/#update-app-metadata

but it seems that is for the Oculus official App store, not app lab, because those instructions dont work. It mentioned things that are not on the pages when clicked as per the instructions.

Does anybody know how to upload a new video to over write the one i already have in the PDP for app lab games?

Thanks
