+   *  - For ERC721 NFTs, each minted token's quantity should always be 1.

+   *  - The total of minted amounts can be different from the input `quantity`.
+   *
+   * Examples:
+   *  - ERC1155: If mintedTokenIds = [1, 2], then mintedAmounts = [10, 20]
+   *  - ERC721: If mintedTokenIds = [1, 2], then mintedAmounts = [1, 1]

+   * @return mintedAmounts The minted amounts according to the `mintedTokenIds`.
