How I make a suspicious block (aka sus sand and gravel) have a custom loottable on my structure?

I think this is something you can do outside of mcreator, like you dont have to code anything but actually make a command for it. But if that isn't the case, then may i ask you, do you know how to make a loottable?

If you do know how, then i believe you only need 1 item in this loottable, then type in the following command: "/give @p minecraft:suspicious_gravel{BlockEntityTag: {LootTable:"archaeology}} Replace the "archaeology" with the registry name of your loottable. and if you want the suspicious gravel to be suspicious sand then just replace the gravel with sand, obviously.
