How to make a Transaction/ Update Balance and mint an NFT using PlayFab and Moralis?

I am using Moralis to integrate Web 3 in my game. I am using unity for game development. I have followed this tutorial https://docs.moralis.io/docs/using-unity-playfab in the docs. I want to add transaction and NFT minting. Where to look for it to achieve this in Unity?

You can use Nethereum to interact with the blockchain and contracts - that is what the Moralis game kit uses.

Thank you for your reply will look into it.
