Can I Watch GoPro VR app on my Samsung Gear VR Headset

I recently purchased the Samsung Gear VR headset.  I have downloaded the Oculus App and such.  I have also downloaded the GoPro VR app, as I work for GoPro call fulfillment.  I would like to know how to watch/use the GoPro app with my Gear VR or is this not possible?

Am I stuck to ONLY Oculus app content?

If there is a thread covering HOW TO, please link me.  Thank you.
