Caddy - letsencrypt TLS files

I recently activated the most piratical TLS feature of caddy for production use for multiple platforms.

I can notice that, generated PEM files are as following per site,

/etc/tls/acme/acme-v01.api.letsencrypt.org/sites/host.domain.com/host.domain.com.crt
/etc/tls/acme/acme-v01.api.letsencrypt.org/sites/host.domain.com/host.domain.com.key

In addition to JSON file

/etc/tls/acme/acme-v01.api.letsencrypt.org/sites/host.domain.com/host.domain.com.json

The question is, what about the ca-chain.cert.pem file? such platforms are expecting root CA.

The full chain is included in each pem file. Is that what you’re asking about?
