How change allow_domains to file separate

There is possible openresty does query in file domains instead write domains allow in nginx.conf?

auto_ssl:set("**allow_domain**", function(domain,renewal)
return true
end)

Start by tracing the allow_domain callback passed to auto_ssl:set and how domains are currently configured in nginx.conf. Determine the intended file format, lookup and reload behavior, then identify the relevant implementation and test entry points; done means domains can be read from a separate file without embedding them in nginx.conf.
