Does anyone know how to close suitelet tab after submit? I tried window.close() and it seems not working. Not sure which part is wrong

I’ve used this: `_context_.response.write(``

<h1>Adjustment(s) Created</h1>

<p id="only"> This window will close in 5 seconds. </p>

<script>

var timeleft = 4;

var downloadTimer = setInterval(function(){

if(timeleft <= 0){

clearInterval(downloadTimer);

document.getElementById("only").innerHTML = "Finished";

} else {

document.getElementById("only").innerHTML = "This window will close in " + timeleft + " seconds.";

}

timeleft -= 1;

}, 1000);

setTimeout(() => {

window.close();

}, 5000);

</script>

``)`

Thanks. I will give it a try.
