Use the Run JavaScript on Web Page action in Shortcuts
Use the Run JavaScript on Web Page action to retrieve specific data from a website, or to modify the contents of a webpage.
The Run JavaScript on Web Page action contains a text field where you write your own script. You run the shortcut from the Safari app.
Note: You can also use the Run JavaScript on Web Page action in SFSafariViewController.
