Passing URL ID to another html link or button on same page

I’m just trying to append the incoming URL ID to another outgoing link on the page. I realize you can no longer add shortcodes to HTML, but I don’t understand the new workaround for that.

The incoming URL is https://www.site.com/survey/?ID=12345

and the link on the page I would like to create is https://www.anothersite.com/?PROJECT=ABCD&ID=12345

The PROJECT parameter is already supplied and needs to stay in the link. The ID However needs to be appended from the above incoming link.

Really stumped and under some pressure! Thank you!!!
