Resources:

import * as ethers from 'ethers'; //V6

//Set one of Hedera's JSON RPC Relay as the provider
const provider = new ethers.JsonRpcProvider(hederaJsonRelayUrl, '', {
  batchMaxCount: 1, //workaround for V6
});

//load ABI data containing the Factory's getPool function
const interfaces = new ethers.Interface(abi);

const factoryContract = new ethers.Contract(factoryEvmAddress, interfaces.fragments, provider);
const result = await factoryContract.getPool(token0, token1, fee); //(token1, token0, fee) will give same result
const poolEvmAddress = result; //address pool
