Adding additional inventory slots to a character

[Wonderlarr]

Hello! Thanks for stopping by my post!

I have a couple mechanics in my mod that use the inventory in some direct way, so I wanted to add a few dedicated slots for these items go in to the default inventory. I took a look at the Hollow Knight mod which adds it's own slot, but the way it added it seemed extremely inelegant, things like a patchwork fix for crashing while using the mod Extra Equip Slots.

I've unsuccessfully experimented myself with AddEquipSlot as part of the inventorybar widget, and messed with inventory_classified prefab, these experiments resulted in both server and client crashes every time so far.

What would be the best way to add extra inventory slots to my character?
