InitializeMint can create NFT by initializing a new Mint with the instruction.

Mint is used to create or "cast" new NFT that are stored in the account, and each has a unique token id, which is incremented by the total supply from The token id is incremented from 1 according to the total supply.

And Mint is also stored in the account, we will call the account stored mint as mint account, and the account stored NFT as NFT account.

Once Mint is initialized, NFT can be created using this instruction mint_authority. mintTo can create NFT using the mint_authority of the mint account at any time as long as the Mint contains valid mint_authority and as long as the number of minted NFT has not reached the maximum supply.
