Share Page Siri Shortcut Question

Hey, I’m trying to create what I see as an extremely basic Siri Shortcut that just lets you open a link in a private tab in Safari from the Share page. I can’t seem to figure out a way to do it, which seems absurd to me. Is Shortcuts really this limited for what to do with a URL in Safari, or is there some sneaky way to accomplish this that I’m just not seeing?
