Sefl-hosted appwrite function domain

Hey all. I'm having trouble hosting my appwrite function domain. First, I already registered a domain say, example.com, and I have configured wildcard ssl certificate and wildcard domain to host my appwrite on this example.domain (appwrite.example.com), and I also configured nginx to proxy_pass appwrite.example.com to localhost. I also changed _APP_DOMAIN_FUNCTIONS in .env to appwrite.example.com. Everything works fine until I deploy a function and a random function ID is assigned to the appwrie.example.com domain. It seems that I have to configure wildcard * to appwrite.example.com. And, the domain section in the function section doesnt have a CNAME.

TL;DR

Developers need to configure a separate domain for hosting Appwrite functions. To do this, they should set up a CNAME record to point *.functions.example.com to appwrite.example.com. Then, configure Nginx to forward traffic accordingly. It's crucial to ensure the function domain differs from the main domain. To resolve issues with random function IDs being assigned to the domain, developers must set up a wildcard domain that passes traffic to Appwrite on localhost.

and how to setup wildcard domain for deployed functions in nginx so it can pass to appwrite on localhost ?
