Was that a statement or a question? You said you "can pull the URL out of there." Or are you asking if that is possible?
Which "get URL" action are you using? This one? This action doesn't get the URL from the current browser. It gets the web page at the specified address, which is different from what I think you are trying to do.
Isn't Edge brand new for MacOS, like a month ago? So I don't know much about it. Does it have AppleScript support?
