Is it possible to vote in the Steam Store using JavaScript?

Question

JavaScript

Hello.
The bottom line is that there is a browser (Mozilla Firefox) with Greasemonkey installed. I'm trying to write a script with which one could "click" on the voting button, after which, in the window that opens, vote ( Steam Store )
This is what the button looks like:

What happens after clicking:

You need to vote for one of 2 sets (I already voted).
I want to say right away that, unfortunately, I almost do not know JavaScript. :(
I tried to click on the button using document.getelementbyclassname, document.getelementbyid, but it didn't help. Maybe I'm specifying the class name / id of the button incorrectly.

As far as I understand, the class here is btn_summersale btn_openvotedialog (please don't throw stones if I'm wrong ).
Is it possible to somehow implement a click on these two buttons using JavaScript?
Thank you. :)

If there is JQ...
$(selector1, selector2).click()
