Autoselect item with TamperMonkey

[parvares]

Hi, I'm using this website:

https://www.bibliotechediroma.it/opac/.do

and trying to autoselect in "Digita o seleziona la biblioteca":

Municipio X > Biblioteca Elsa Morante

I used this script in TamperMonkey, where am I wrong? Thank you!

(function() {
    'use strict';
document.querySelector("button[class='syw-comboselect-trigger']").click();document.querySelector("li[data-group='GR_10'] a[title]").click();document.querySelector("li[data-cd='RMBO2'] a[class='select']").click();
})();

What exactly is your problem?

The page didn't react, now solved adding a setTimeout delay. Thanks!
