How can I remove secondary roles block?

I used this solution for myself.
Hope it helps others.

var userURL = window.location.pathname.split(‘/’);
if (userURL[userURL.length – 1] == ‘user-new.php’) {
var secondRoles = document.getElementsByTagName(“th”);
for (var i = 0; i < secondRoles.length; i++) {
if (secondRoles[i].innerText == “Secondary Roles”) {
secondRoles[i].parentElement.parentElement.parentElement.style.display = “none”;
}
}
} else {
}
