help mod porting to SFM

[KandiTheOcto]

So I would like to get some models from Splatoon 2 and 3 mods (i also have no way of contacting the creators to ask for permission, so i will say sorry and link and credit them if i ever port the models), and the models (they are some hair models and a couple haori models, so for now i will refere to them as items) are bfres.zs format, but when i open up the models in Switch Toolbox, there are no models in the models folder of the items.

and on top of this, there is only one tutorial on how to do this, but i think others have been successful in porting models, so, can someone help me??
(also here is my plan for conversion: bfres.zs to .dae (there is no fbx or other normal blender formats available except for .dae, then .dae to .mdl and .vtf)
