How do you add Advanced Search Add-on to your site

I’m trying to add this to my site however I’m finding your documentation vexingly circuitous. I understand that its an addon, and I do have that active, and that it extends the normal Geodirectory search widget. However when I try to use that widget it is unchanged. I try looking for the options for this widget and I don’t find any. I try looking at your documentation here: https://wpgeodirectory.com/downloads/advanced-search-add-on/ however it then directs to you the V1 GeoDirectory Search: https://wpgeodirectory.com/docs/gd-search/ even though its an extension of the GeoDirectory V2 plugin, so follow the link at the top of the page which takes me here https://wpgeodirectory.com/docs-v2/ and after much searching all i can find is a single sentence description of the gd_search shortcode. This is an absolute mess. I’m an actual developer and I’ve spent over an hour trying to figure out how to just get this thing to exist, nothing more than that, and still I have to resort to asking you for help. I strongly urge you to take a look at your documentation because it is lacking.
