To clarify, you're referring to this portion of the article:
Newsom then appeared on the Shawn Ryan Show, another far-right podcast, where he expanded his rhetoric. He downplayed transgender people’s pronouns, saying, “I'm trying to understand as much as anyone else the whole ‘pronoun’ thing.”
Digging into the detail link gives a smidge more context on the quote, but not much...
Naturally, Ryan’s line of questioning didn’t stop with sports, either. He suddenly turned to the idea of trans kids in general. “Is eight years old too young?”
“The trans issue for me is so novel,” Newsom said. “I'm trying to understand as much as anyone else the whole ‘pronoun’ thing.”
I don't interpret that as genuine confusion over trans identities and pronoun use. That's straight-up pandering; doing a pantomime of having a boggled mind to endear himself to the host and his audience.
It's a transparent falsehood; disingenuous, cheap and ridiculous. These are not qualities befitting of someone seeking the highest office, let alone at a time when the nation teeters on the brink of fascism.

I sat in on a seminar by Advocates for Transgender Equality who explained a lot of key details of receiving transgender medical care.
Their primary message was "you'll almost certainly get denied initially, and then have your appeal denied as well. That's when you appeal again, to a third-party oversight board, and that's where you will almost certainly win."
The process is arduous and designed to frustrate you to the point of giving up. Don't give up.
