Differentiating between different headsets?

Developing a VR app that aims to support the Oculus Quest, Go, the S and potentially Vive and I was wondering the easiest way to detect which headset/setup was being used.

I'm not entirely sure of the process as I've never released anything for VR through the stores yet - but would I need separate versions of the app for each platform or would I need a code in the app to check which headset is being used and act accordingly? (swap out controller models and such).

Thanks!
