Max supply is displaying zero value on etherscan

How do I indicate that there is a max supply of 3? This is all the NFTs in the collection and that will ever be. No more to be minted/created for this. How is this done instead of not displaying a max supply?

Up to you how you want to illustrate this. If you would like to title your tokens in a certain manner, add to the description etc.

How do i then show the max supply? where do I do this? I have attached an image to indicate what I mean. Thanks
