If you run the same shortcut on the same webpage again, Shortcuts does not show the prompt again.

Once you tap Allow, the shortcut runs on the specified webpage. This means that the shortcut can access potentially sensitive data from the webpage, such as passwords, phone numbers, or credit card information. When you run a shortcut that contains the Run JavaScript on Webpage action, a prompt is displayed informing you that the shortcut is about to interact with the webpage.

The Shortcuts app takes a few measures to make sure you run your JavaScript shortcuts securely and privately. When you allow a shortcut to run JavaScript on a webpage, that shortcut can access all of the information on that webpage-including potentially sensitive data.
