404 redirect for subdomains

I would like to configure the following feature: in case of a subdomain that does not exist, cloudflare redirects the user to the main page. I have configured a redirect rule to exclude all existing domains. So:

Redirect to page: astoria.studio if:

Address is not api subdomain
Address is not download subdomain
... etc.

Unfortunately, this doesn't work. If you type e.g.

kjwevhfouqwb.astoria.studio,
blablabla.astoria.studio,

the user is NOT redirected to the home page.

How to configure this feature?

Please don't use URL Fulls with Start with, use

Hostname

Hostname

and is not inis not in and type out your list of just raw hostnames like api.example.comapi.example.com and add option, repeat until has all

For it to work as well you need a wildcard proxied record

AAAA

AAAA

100::

100::

Proxied

Proxied

, create, wait a bit, try on a random domain, should be set. Wildcard get slightly messy though. For example if discorddiscord exists in any capacity, even just a TXTTXT, then anything under it like gihgiohgiohg.discord.example.comgihgiohgiohg.discord.example.com won't redirect unless you make *.discord.example.com*.discord.example.com
