How to trigger 1st Person animations ?

[Benjou1]

So basically I would like to know how to trigger the "relaxing" AFK animation when you have your weapon in hands and not playing.

 

I tried to search in the idle section some records that could be played and try to trigger it with player.playidle but maybe it's only for the third person.

I tried to open some ba2 archives and browse blindly, same with the Fallout.esm but I have just no clue.
