So, When configuring for a Command to add I am getting the initial text and cost but it is not showing what the actual item is. As well, I am using Backpacks and I wanted to give permissions to use an extra slot of 6. I used the command  /rewards add command Backpacks oxide.grant user $player.id backpacks.use.1 5000  and it is registering a price, just not giving the actual command or even what it is

Ok, so I have this in operation but I am missing the left side notification of what the actual item[s] are. Is there a way to add an image or icon to the left where those two left horizontal has marks are? Or..At least tell me the details on where to add the Item Identifier?
