How to set up site parsing from JavaScript to C#?

Question

JavaScript

Good afternoon kitties. Please help me with this question. There is a government website that posts documents on its website. The site has a JavaScript module that displays links to documents in the table.

To get a link, you need to open the drop-down list and select the required section with the document. Initially, the source code of the page does not contain all the links to the files. They are generated by the script. Moreover, it generates these links even without access to the Internet. You just need to download this module. It is necessary to somehow open all the drop-down lists so that the script gives links to documents in the source code of the page and I can pull them out with my parser. Tell me, is it possible to open all the drop-down lists with some script? I'm not very good at JavaScript. I don't know if links can be posted. If anything, the link to this section of the site is in the screenshot.
