[squid-users] Is there a way on client to show proxy's certificate?

because I'm doing the explicit proxy for https on this proxy server. if I
configure
"https_port 3129 ssl-bump ...", then I get this error when doing the https
proxy:

2019/12/22 22:07:15| FATAL: ssl-bump on https_port requires tproxy/intercept
which is missing.

so this to me means, i can only configure https_port if I'm using the
intercept method, which I'm not.
Or is there a way to listern to the https_port with explicit proxy?

The above command works for me, but I only get the certs from the real host,
not the proxy server itself.

thanks.
