contract First {

    function test() external {
        emit Winner(msg.sender);
    }
}

contract Second {
    event Winner(address);

    function attempt() external {
        require(msg.sender != tx.origin);
        emit Winner(tx.origin);
    }
}

My idea for Second was to call this contract from another contract but it doesn't work.

Here's my code

// SPDX-License-Identifier: MIT

pragma solidity ^0.8.0;

contract Second {
    event Winner(address);

    function attempt() external {
        require(msg.sender != tx.origin);
        emit Winner(tx.origin);
    }
}

contract SecondCaller {

    Second public mySecond;

    constructor(address secondAddress) {
        mySecond = Second(secondAddress);
    }

    function secondCall() external {
        mySecond.attempt();
    }
}

At deployment I specified ´0xb4c4e0c94d539b347f5c1d5693cd49fd677464ff´ as the secondAddress.
