How do I download VR games on VR?

Excuse me, could you please elaborate on the process of downloading VR games onto a VR headset? I'm particularly interested in knowing if there are any specific steps or requirements that I need to follow in order to successfully install and play VR games on my device. Additionally, are there any recommended VR game stores or platforms that you would suggest I use for this purpose? I'm eager to get started with VR gaming and would appreciate any guidance you can provide.
