Check Minecraft item in inventory 1.16.4?

I want to build a casino in Minecraft (1.16.4).

You should only get (give) iron lumps via the command block if you still have honeycombs in your inventory.

Additive:

Was intended as an exchange of iron lumps for honeycombs (/ give & / clear).

Replace Item would be a solution.

However, this would then have to be linked to a scoreboard and that is a bit more complicated.

Here I have something else:

/ execute as @p [nbt = {Inventory: [{id: "minecraft: honeycomb"}]}] run clear @s honeycomb
/ execute as @p [nbt = {Inventory: [{id: "minecraft: honeycomb"}]}] run give @s iron_nugget

Wtf it is much easier

True but I would have done it now with an execute command, and then the item replact.
