Where can I find lichess code for the "request a computer analysis" code

In a Lichess finished game, if you go to the analysis board, you have the button "request a computer analysis" which, with an absolute lack of suspense, trigger a computer analysis. I would like to know where exactly in lichess.org/source the source code for this can be found.
(In fact I would like to write a script on my computer doing this for a PGN file in input.)

You can import the pgn file and analyse the games afterwards.

I should have been more precise. I want to batch analyze lots of games. Hence I don't want to do it manually game per game. Hence the need for the code.

I looked already here and did not find it. Some help could be useful

Also, I want to use my local (i.e. on my local machine) stockfish (or possibly lc0) for the batch analysis, not analyses from machines on the fishnet network.

I think all the code's stored in GitHub.

I know that all the code is stored in github. :) (You remark in my original question that I am pointing to that code.) I just can't find where the piece of code in the github is. Even narrowing to fishnet did not help me.

Oh, sorry.

github.com/lichess-org/fishnet/blob/master/src/stats.rs
I really am a noob at programming. But I found something related to analysis.
