ERC-20 – Error ‘Execution Reverted’ When Calling TransferFrom() on OpenZeppelin

This is my following Code. I am using the Rinkeby network.

//SPDX-License-Identifier: MIT
pragma solidity ^0.8;

import "https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC20/IERC20.sol";

contract TransferDAI{
    IERC20 public dai;
   
    constructor() {
        dai = IERC20(0x5592EC0cfb4dbc12D3aB100b257153436a1f0FEa);
    }
    
    
    function Transfer(uint _amount) external {
        dai.transferFrom(msg.sender, address(this), _amount);
    }
   
    // Some extra functions for now...
    function getDaiBalance(address _address) external view returns(uint) {
        return dai.balanceOf(_address);
    }
}

I am not able to transfer Dai to the contract address. Although I can view getDaiBalance and see the correct amount of DAIs.

Any lead will be helpful. I tried using dai.approve(msg.sender,_amount) it wasn't helpful.
