Problem

In R shiny, it currently displays a modal in this situation. I do not like the modal and would prefer a less invasive option.

Solution

I propose that a notification is shown and the user's clipboard is updated with the URL value.

Alternatives (Optional)

• Showing a modal: It blocks the whole screen. When you click "bookmark", it is fair that you want the URL now. Not trying to exit a modal to get back to your app or having a modal block your app. I want the url now and without any effort.
• Throw an error: This would cause the app to crash. Crashing is bad Mkay.
• Do nothing: Worst of all three is to do something where you expect a reaction and nothing happens. This is difficult to debug and very frustrating to figure out.

Start by locating the code path used when no on_bookmarked handlers are registered and the existing modal behavior. Read the notification and clipboard integration points, then verify that bookmarking shows a notification and copies the URL without blocking the app.
