Can not verify Smart Contract with @chainlink

I can not verify my test smart contract on BSC Main Network using @chainlink.

// SPDX-License-Identifier: MIT
pragma solidity ^0.6.7;

import "@chainlink/contracts/src/v0.6/interfaces/AggregatorV3Interface.sol";

contract PriceTest {
    AggregatorV3Interface internal priceFeed;
    
    constructor() public { 
    priceFeed = AggregatorV3Interface(0x0567F2323251f0Aab15c8dFb1967E4e8A7D42aeE); // for BSC Main Net

    }
 
   function getLatestPrice() public view returns (uint256) {
        (,int price,,,) = priceFeed.latestRoundData();
        return uint256(price/100000000);
    }
     
}

What I have done :

1. Make Flattened file and put in the contract code using truffle-flattener. I did it before for a test net and it's ok.

2. Copy ABI from remix and pasted to abi.hashex.org

But I tried many time end up with problem in verifying the contract. I think I am not really understand how to put constructor parameter correctly to get the ABI auto-parse. I am quite new to smart contract. Need learn more from experts.

My contract :
