How to start with settingup project on metronics demo-2 | Vue-Sass

Hi Team ,

I have purchased a metronic theme, and started with setting up a project taking demo2 as a reference for userInterface . While making changes i found some missing codebase in downloaded folder. I am not able to find all menus item what is there shown into live preview List of item not available:
1: Ecommerce app
2: User Management app .
3: Invoice Management & few more, how to find them?
4: Metronic is using typescript alongwith vue in downloaded project folder, how to get javascript with Vue instead of typescript in project folder.
5: Proper documentation is missing as per vue project.

Any comments will be highly appreciated.
Looking forward for solutions
