There are 2 ways to achieve this:
1. Browser-based method
Easy to setup, but relies on the Browser's Local Storage.
Meaning, if they started filling out your form using Chrome, left their desktop/laptop, went back and re-opened the form on Firefox/Safari, then their progress is lost. Using the same Chrome browser again would continue where the user left off.

2. Session parameter method
Quite complicated setup and requires 2 forms to make it work.
Form 1: The first form where the user will need to fill out the name and email field. The session URL will be created here and we will use the email field as the session ID.
Form 2 (Main Form): This is the main form where all the necessary and important fields we need to collect. The main form needs to have page break, please also note that the progress on each page will only be saved when the "Next" and "Back" button is clicked.
