Web browsing, remote click a mouse over (hover over) button

I'm trying to figure out how to click a "mouse over button" on a website via excel.
I can easily click buttons on other web sites via Excel, but this mouseover button is somehow different.
I've spent over 40 hours reading posts from others and trying different methods. None have worked.
I've read numerous posts from others trying to do the same thing but none have posted a "solution".

Is it possible?

I posted this same request on ozgrid for several days. I got no replies.

The project:

I'm accessing a financial services password protected web site, so I can't provide access to it, obviously.
The VBA code successfully navigates to a particular screen that lists client current "open orders".
The goal is to download this screen as an excel.CSV file by clicking the "EXCEL EXPORT" button on the screen.

A panel of three buttons are related to one another: PRINT button | EXPORT button | EDIT button

The VBA code and HTML that is displayed when I "inspect" the "EXCEL EXPORT" button are included in the attached excel file.

Thanks for your help.
