Is there anyway that i can view a gopro live stream on my app

I have mounted a gorpo on a bluetooth car. The car works fine with the app i made
Is there a way in which i can see the live footage of the gopro on my app
(Gopro has a feature to preview footage via the gopro app)

Possibly, but we need all the relevant technical information you have, starting with the car and the go-pro's manual.

Others have achieved the same with an ESP32 based video camera.
