Literature on modelling of the antiproton-nucleus annihilation in FLUKA

Dear FLUKA experts,

I am preparing a publication on antiproton-nucleus annihilation where multiple models, among which FLUKA will be compared to measurements. For this reason, I would like to write some details about the way FLUKA handles the antiproton-nucleus annihilation. I tried and failed to find anything more detailed than this explanation on the old forum:

https://www.fluka.org/FLUKA/web_archive/earchive/new-fluka-discuss/7352.html

Could you please provide any kind of documentation with more information?

Thank you in advance!

Unfortunately, no detailed documentation expanding on the outline you refer to is publicly available at the present time.
