How to develop an offline application on BitrixMobile?

Question

Subject.

Here is how to create an offline application page: https://dev.1c-bitrix.ru/learning/course/index.php...

And what's next? How to develop, because if I create such a page, I will simply get cordova and bitrix_mobile_core loading errors.

In particular, the question is - how to be, for example, with debugging push notifications, because in order for them to work, scripts of the pnp module must be loaded, but naturally, none of the Bitrix scripts will work with the described approach.

I have little experience with development for BitrixMobile, never with offline mode at all.
