Not possible to register .ch domain…how to connect?

Hi all,
I have been really happy dealing with Cloudflare in the past with .com domains and my own apps…but I realized that I cannot enter a .ch domain registrar in the platform.

Do you know if there is any possibility to connect a .ch domain through DNS?
Would I have to require a hosting service in case I want to build my own app in this specific case?

Thanks in advance for the help!
