How to see the https response headers and response bodies in squid?

[monterry]

The pfsense web UI (Services -> Squid Proxy Server -> Real-time) allows us to see the https requests originating from the clients under pfsense. But is there a way to see the responses headers response bodies and request bodies also?

I am trying to make a test setup for testing my web application hosted in a staging server but I am far from being an expert. Trying to read my way through, any pointers highly appreciated.

In my setup, pfsense is installed with squid proxy, which is set to transparent proxy mode, and is configured to do SSL MITM filtering in the LAN interface.
