How to see certificate for intermediate CA in Keychain?

When I check details of a certificate I only see information about the certificate itself. Is there any way to see the issuer’s certificate? In my case it’s an intermediate CA. The certificate that I care is for S/MIME (hence the tag), but I think this should apply to all kinds of certificates in general. I think there should be a way because it’s very intuitive in Windows. Also Chrome on macOS displays the full chain for websites. I think Keychain.app has this information because it labels the certificate as a verified one.
