I use opensea.io for create nft tokens. I want create 100 tokens and then create redeem mechanism on my site (allow download music). I created contract using: "?enable_supply=true" https://rinkeby.etherscan.io/address/0xee45b41d1ac24e9a620169994deb22739f64f231
But I can't get Token Id:
seems theres no method tokenByIndex. I need know TokenId for each item, it for my redeem mechanism. Could I do it with this contract or I need use custom contract?
