How to interact with a smart contract with ethers.js?

const tokenContract = new ethers.Contract(contractAddress, tokenAbi, connection);
const transaction = await tokenContract.balanceOf(req.body.address)
const data = Promise.resolve(transaction)
data.then(value => {
    const result = ethers.utils.formatUnits(value, 18);
    console.log(result)

});
