Client script mask code not working

Hi, a have a web form and some fields that need masks, I tryed to put a client script, but it’s not working.

frappe.require(“https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js”);
frappe.require(“https://cdnjs.cloudflare.com/ajax/libs/jquery.mask/1.14.11/jquery.mask.min.js”);

frappe.web_form.after_load = () {
frappe.meta.get_docfield(‘company’, ‘cnpj’).on_make = function (control) {
$(control.input).mask(‘00.000.000/0000-00’);
};
}

Somone can help to find whats wrong?

I’m also looking for this feature. Has anyone found a way of masking a text fieldtype or is validating it after the control has lost focus the only way of doing it?
