openssl - How to extract the ssl issuer name with openssl

Question

I have tried various combinations of openssl commands in order to extract ONLY the name of the SSL issuer of a specific domain name but this was not possible. I have also made a research in order to found ready solution but I was not lucky.

I know the following command will provide us a lot of SSL cert information including the name of the ssl issuer: openssl s_client -showcerts -verify 5 -connect example.com:443

Is it possible with a simple openssl command to retrieve only the name of the ssl issuer(e.g. Let's Encrypt or DigiCert) by using only the domain name?
