How to HRT in Switzerland as a foreigner 2024?

Hello, I'm 21 y.o. italian trans girl and I live in Kanton Zug , Switzerland for work.

I recently got my gender dysphoria certificate from a hospital ward in Italy, after a year and a half of waiting. Hopefully doctors here accept the document. How can I start HRT now?

I tried talking to checkpoint Zürich and they gave me the contact of a trans friendly endocrinologist here in my Kanton. He's called Niklaus Flütsch.

Can I go straight to the endocrinologist and start treatment or are there extra steps that I have to take?

Hopefully somebody can help me figure this out haha. Ty❤️
