I would say ditch tribaldex and use our Layer 1 Hive native NFT system over at darkcloaks.
Way easier to use and full api's docs to do what you want.

Hit me up in discord if you want to chat more about it.
We run our games on it and we are in the process of onboarding Crypto-shots to our system.
No fees to build on, no licneses to buy etc...
