how to get all user address on the transactions with a smart contract?

Question

just started learning this and trying to get all addresses that have been interacted with a contract, I am planning to pull out all events, and then get the addresses from there? any advice if this will work? thanks

async function getUsers() 
    {
        var allTransactionsHash = myContract.events.allEvents.transactionHash();
        var curBlock = await web3.eth.getBlockNumber();
        var allUsers = []; 
    
        while (curBlock !== GENESIS)
        {
          var txns = web3.eth.getTransaction (allTransactionsHash);
            for (var j = 0; j < txns.length; j++) 
            {
            var txn = txns[j];
            allUsers.push(txn.from.toLowerCase(), txn.to.toLowerCase());
            }
        }
        return allUsers;
    }

The best solution would be to add events that should be emitted only for the specific functions in the contract, which you would want to track. You should always keep I'm mind that the code must be as simple and as short as possible in order to be gas-efficient.
