How to create a subdomain for Symfony?

Question

symfony

Hello.
I have never dealt with subdomains, but then I wanted to make a personal account on Symfony for companies available at the URL client.site.ru
Please tell me how to create and configure a subdomain for Symfony?
Do I need to make any settings in ISPManager?

Here about routing: symfony.com/doc/current/routing/hostname_pattern.html
For this to work in dns, you need to have an entry for each subdomain or for *.
