[SOLVED] How to create a signer in cloud and sign transactions?

Hello,

I have this code from the documentation about calling a function from the cloud. How to change it such that I can sign a transaction with my private key and write it to the contract on the cloud?

let’s say my private key is = XXXXXXXXXX;

Moralis.Cloud.define("run_contract_function_with_web3", async (request) => {
  web3 = new Moralis.Web3(
    new Moralis.Web3.providers.HttpProvider(
      "RPC URL"
    )
  );
  const abi = [
    {
      constant: true,
      inputs: [],
      name: "name",
      outputs: [{ name: "", type: "string" }],
      payable: false,
      stateMutability: "view",
      type: "function",
    },
  ];
  address = "0x2170Ed0880ac9A755fd29B2688956BD959F933F8";
  const contract = new web3.eth.Contract(abi, address);
  const name = await contract.methods
    .name()
    .call()
    .catch((e) => logger.error(`callName: ${e}${JSON.stringify(e, null, 2)}`));
  return name;
});

I’m stuck with this for days. Please help me.

Thank you.
