An article link can describe the reading view you want to share. It does not need to include the other windows in your workspace.
Open the notes, move or resize the windows, then choose Copy the link from this article's window menu. The copied address opens this article alone. Your current arrangement stays in the address bar, where you can copy it to share the whole workspace.
You can also follow or copy the article link directly, including without JavaScript.
This window belongs to your workspace. The article link leaves it out.
