Video Game Dev using Godot Engine + MetaMask Polygon or other

I am using Godot Engine for game dev and I would like to use NFTs in my game as a playable card.
Does anyone know how I would achieve this in Godot Engine + Metamask?
How can my game connect to a players wallet?
How to put their NFT into the game?
Or where to start?
I’m mostly using polygon/Matic chain but Im open to other chains preferably with a no/low gas functionality.

Thanks for your help:)
