How do I setup on a recent device?

I'd like to ask for help or some guides that I might have not found yet on installing the necessary software for GearVR on my phone.

I have the SM-R325 model which is the most recent as far as I know and I'm trying to install on my Galaxy S23 Ultra.

I prefer to not root or install another OS on my phone but I may consider this if I have to.

I could just buy a used S10+ and automatically start the setup process but buying another phone for it would be my last resort.
