To add more slot, you just have to modify the following line of code from LyraArmorBarComponent.h
UPROPERTY()
int32 NumSlots = 6;
Update the slot amount to your preference.
Then go to Widget, W_ArmorBar and add another ArmorSlot to the bar.
Finally, assign the new slot the corresponding index.
In this case, the index must be 6, it would correspond to the 7th item.
and that’s it!
You already have a widget assigned, for the corresponding slot!
