"squid -k parse" will tell you the option is called "intercept" now.
Transparency is something different.

Missing the intercept option here.

Also, "squid -k parse" will tell you the option is called "ssl-bump".

Also, "squid -k parse" will tell you the option does not exist. It looks
like you are wanting the option "server-first".

Try to avoid this violation of TLS.
The server-first feature makes it mostly unnecessary now.
