Is it possible to make WebView work without internet?

Question

Android

There was a task to make a small application that will load a page from the server with a form by URL into the application, and when filling out the form, save the data on the device.
Just as importantly, the form is relatively non-standard and works with a lot of Javascript adding table rows. And the decision suggests itself to use the already existing javascript on the server.
In the absence of the Internet, it is necessary to take data not by URL, but from local storage.
Tell me, is it possible to implement this using the WebView component, or will I have to make a native application?

Really. Just did it today for a client. You need ServiceWorkers.
