Lean Software Development Team Example?

Could someone give me an example or like a real case study on lean software development, where the team like "Yeah, we wanted to take a lean approach, then we did it, this is what we did, and it worked well".

Was searching online and all I saw were vague definitions of lean or "in abstract do this" articles, or "this company has this process that they came up with and after the fact we decided to describe it as lean" scenarios.

Also seeing a lot of "this version agile framework is kind of lean, so we decided to say it's lean" articles.. it's kinda weird how hard it is to find a working example.
