Hi, i have a problem if i try to verify my contract source code i get this error:

ParserError: Source "@openzeppelin/contracts/token/ERC20/ERC20.sol" not found: File import callback not supported
--> myc:5:1:

| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

i am using this contract:

// SPDX-License-Identifier: MIT

pragma solidity ^0.8.0;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";

contract MonopolyCoin is ERC20 {
    constructor() ERC20("MonopolyCoin", "MONO") {
        _mint(msg.sender, 25000000000000 * 10 ** decimals());
