Sending Headers with Lighthouse

I am using Lighthouse from command line to audit my website.

In order to access my website from Chrome, I need to send custom headers (Using Modify Headers Extension).

However, when I am launching lighthouse from command line:

lighthouse http://x.y.z.a:888

It opens a new Chrome window (which has no Modify Headers Extension) and thus requests are sent without headers, without which the website is not accessible and hence not auditable.

Any suggestions as to how to send custom headers with lighthouse using command line?
