My personal tip is to slow your breathing, slow it down enough that you breath too slow and feel a bit deprived from oxygen. Then slowly breath faster but try to keep it as low as possible.

I think (but I am not an expert in this) it slows down the heart and with that, allows you to fall asleep easier.

You probably can't really "feel" oxygen deprivation from that breath work. More likely you're feeling hypercapnia.

A resource that I've been using lately that has some details regarding this particular part of the breathing process: https://midlmeditation.com/meditation-for-anxiety
