What pen is actually used for Aspire A3SP14-31PT

I have an Acer Aspire 3 Spin 14 computer and an Acer AES 1.0 Active Stylus. The Aspire is listed as having "Active Stylus support," as far as I can tell the two products should be compatible. However, I can't figure out how to actually get the stylus to work.

On the side of the stylus, I have inserted a battery in the correct orientation, and don't see anything else I should need to do for it to function, or to independently check that it is functioning.

On the side of the laptop, I have considered that there is some additional driver/software I need before it will register stylus inputs that wasn't preinstalled. However, I didn't find anything that seemed relevant under the Product Support page's Drivers and Downloads for the Aspire A3SP14-31PT, and I'm not sure where else I would look to find out and get what is needed.

I have also considered that the two products simply aren't compatible with each other, but in that case I am unsure how to find a stylus that is compatible with the Aspire's "Active Stylus support." I'll upload a photo of the stylus I bought. I just can't find any clear answer 😕

Thank you for any help/suggestions you can provide!
