What is the road to tech?

I’m a newer open water diver and am absolutely in love with it. My dream is to go CCR/Cave which I want to do in 5+ years. Just curious what the pipeline into tech/CCR looks like? Do you need to be rescue or master to get into tech? And do you need to do tech on OC before going to CCR? Not trying to rush into it but I’m just curious. If you could speak on your experience getting to tech/CCR/cave I would appreciate it.
