I'm trying to upgrade my nft smartcontract (NFT.sol)
After deploy proxy this contract, I get proxy address and use at another smartcontract to mint NFT like this:

2. Item.sol

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

import "hardhat/console.sol";
import "@openzeppelin/contracts-upgradeable/proxy/utils/Initializable.sol";
import "@openzeppelin/contracts-upgradeable/access/OwnableUpgradeable.sol";
import "@openzeppelin/contracts-upgradeable/token/ERC20/IERC20Upgradeable.sol";
import "@openzeppelin/contracts-upgradeable/token/ERC20/utils/SafeERC20Upgradeable.sol";
import "@openzeppelin/contracts-upgradeable/security/ReentrancyGuardUpgradeable.sol";
import "@openzeppelin/contracts-upgradeable/token/ERC721/presets/ERC721PresetMinterPauserAutoIdUpgradeable.sol";

contract Item is
    Initializable,
    OwnableUpgradeable,
    ReentrancyGuardUpgradeable
{
    ERC721PresetMinterPauserAutoIdUpgradeable public nft;

   function initialize(address _owner, address _nft) public initializer {
        __Ownable_init();
        transferOwnership(_owner);
        nft = ERC721PresetMinterPauserAutoIdUpgradeable(_nft);
    }

    function mintOneNFT() public nonReentrant {
        address buyer = msg.sender;
        nft.mint(buyer);
    }
}

When i call mintOneNFT:
It has an error like this:

Error: VM Exception while processing transaction: reverted with reason string 'ERC721PresetMinterPauserAutoId: must have minter role to mint'

So, How I grantRole ADMIN and MINTER for MyNFT to mint success?
