Unity Vimeo Video SDK Oculus Quest

I'm new to Unity and Quest 2 development. Using the Unity Vimeo VR 360prefab I am able to successfully run it using with the Oculus OVRCameraRig using the Oculus link cable. The video plays in the headset in this mode. However, when I build and run the app standalone in the headset, all I get is a gray screen. I have been unable to figure out how to get it to work as a deployed app. Has anyone else experienced this and/or could you please tell me what I should do. I would really appreciate any help.
