Not able to sign transactions using Ethers and Wallet connect

[samatvalive]

I have a problem with initialize contract with wallet connect provider. My task is to call write operation of Smart Contract. I'm able to perform all operation with metamask web enabled extension, but with wallet connect write operation not happening

Here how I'm doing for metamask web enabled extension

const contractAddress = require(`../../artifacts/${version}/contract-address.json`)
const TestPool = require(`../../artifacts/${version}/Samatva.json`)
const smartContract =  new ethers.Contract(
    getAddress(contractAddress.TestPool),
    TestPool.abi,
    ethers.providers.Web3Provider(window.ethereum).getSigner(0)
);

And this is how I'm doing for wallet connect

  const providerOptions = {
        walletconnect: {
            package: WalletConnectProvider,
            options: {
                infuraId: "8f50c72381e64a199c06c12a288067df"
            }
        }
    };
    const web3Modal = new Web3Modal({
        cacheProvider: true,
        providerOptions
    });
    const providerConnect = await web3Modal.connect();
    const provider = new ethers.providers.Web3Provider(providerConnect)
    const Pool = require(`../../artifacts/v2/Pool.json`);
    const smartContract = new ethers.Contract(
        getAddress('0xBba810Edf607706EEfB8F185436cCB6a6a8566BE'),
        Pool.abi,
        provider
    );
    smartContract.totalPoolContribution().then((totalContribution) => {
        console.log('totalContribution', totalContribution.toString());
    }, error => {
        console.log('Total Contribution', error)
    })

But the issue is, this code is working for read operation only, in write operation, I'm getting error -> Invalid Signer or provider

Have you tried passing signer to the contract? Provider only offers read-only access.

const smartContract = new ethers.Contract(
        getAddress('0xBba810Edf607706EEfB8F185436cCB6a6a8566BE'),
        Pool.abi,
        // use signer, not a provider, for write access
        provider.getSigner()
    );
