How to remove leetcode premium problems from your problem list

For PROs

var x = document.getElementsByTagName("tr");
var sum = x.length;
for (let i = 0; i < x.length; i++) {
    if (x[i]["cells"][2]) {
        if (x[i]["cells"][2].firstElementChild.getElementsByTagName("span")[1]) {
            if (x[i]["cells"][2].firstElementChild.getElementsByTagName("span")[1].attributes[3].value === "Subscribe to unlock") {
                x[i].hidden=true
                sum--
            }
        }
    }
}
console.log(sum)
