In my personal experience, I would use code like this to track the result of a transaction:

=== Your Code Parameters === 
.....

console.log("============================");
console.log("Interacting with Collection Contract: \n" + contract_address);
let seqno: number = await wallet_address.getSeqno();
let transfer = await wallet_address.sendTransfer({
    seqno: seqno,
    secretKey: keyPair.secretKey,
    messages: [
        internal({
            value: toNano("0.75"),
            to: contract_address,
            init: { code: init.code, data: init.data },
            bounce: true,
            body: packed, 
        }),
    ],
});



console.log("Transaction sent. Waiting for confirmation...");
let intervalId = setInterval(async () => {
    let seqno2 = await wallet_address.getSeqno();
    if (seqno2 > seqno) {
        console.log("✅ Transaction confirmed!\n");
        clearInterval(intervalId);
    }
}, 1000);

To wait for the seqno back, you can confirm that the transaction has been packed by the validator. I hope this is helpful."
