Considering that making a LUA to minimize BP's needs very little skill, I doubt you have even tried. It really is not that difficult.
What is so hard about this?
lua code:
GoldBp = "red backpack"
Self.OpenMainBackpack(true)
wait(750,1000)
Container.GetFirst():OpenChildren(GoldBp)
wait(300,800)
Container.GetByName(GoldBp):Minimize()
wait(200,400)
