How do I synchronise spawning of every node inside this inventory system in multiplayer?

Godot Version

Godot 4.7.2.stable (Steam version)

Question

I need to synchronise spawning of every node inside LeftHand, RIghtHand, and inventory slots 1-6 when a player joins. MultiplayerSpawners don’t work for some reason, idk why, i hooked them up before with both the “Item” scene and the “Node” scene (whose names are actually the Mp5 Magazine and the Mp5 itself. If a player puts an item in their inventory then it isn’t synchronised once a player joins
