Segment visitors whose browser is headless

Hello,

A lot of modern web tools (Lighthouse, PageSpeed, etc) use headless browsers and it seems there isn’t a way to segment them out of my metrics, as the Browser field in the segmentation form only accept the browser initials (FF, CH, etc). Am I missing something?

I have searched for a similar suggestion or thread and couldn’t find, so sorry if it’s been posted already.

Thanks!
