Simple Google App Script to import data into google sheet

Job ID: 32578238

Budget: $10 – $30 USD

The App Script Code should do the following simple stuff
- Clean all data of the existing spreadsheet
- then import the full contacts detail from https://contacts.google.com/ into that sheet (roughly 2'000 contacts).
I'm looking for the app script code doing this.
I found a lot of documentation and examples but non really worked the way I want to get all the fields of the contact group "My Contacts" into the sheet .
Documentation of the API

This is the first quick projects. Some addition will follow if I'm happy (upload functionality etc).
