How to use UpKeep Automation Payable function In Chainlink

Question

I want to send native ETH to another smart contract address using a function. But when I try to send using payable(toaddress).send function or call value function it throws error. And say that I have to use use Payable function to send to another address.

`solidity

function performUpkeep(bytes calldata /* performData */) external payable override {
    //call
      (bool sent, ) = forgreenAdd.call{value: 10000000000}("");
}

`

I have tried with some functions with payable. All of them worked perfectly. But when I try to use payable for performUpkeep. It does not work.

The contract that you should automate is the one that is going to send the money not the one that is going to receive, so think of that I create 2 possibilities that you could do:

Receiver.sol

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.9;

contract Receiver {
    receive() external payable  { 
    }

    function giveMeMoney() external payable {
    }
}

Sender.sol (Automate this contract using Chainlink)

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.9;

interface IReceiver {
    function giveMeMoney() external payable;
}

contract Sender {
    address receiverAddress;
    IReceiver receiverContract;

    constructor(address _receiverAddress) {
        receiverAddress = _receiverAddress;
        receiverContract = IReceiver(_receiverAddress);
    }

    receive() external payable  { 
    }

    function sendEth(uint256 amount) public {
        if(address(this).balance > amount) {
            payable(receiverAddress).transfer(amount);
        }
    }

    function sendEthWithMethod(uint256 amount) public {
        receiverContract.giveMeMoney{value: amount}();
    }
}
