Hello,
Google Chrome Extension Expert here! I've checked your reference example and due to my expertise, I can certainly develop a chrome Extension where a user can collect all the data from LinkedIn and extract the leads.
Kindly check below some of the examples of Chrome Extension along with data scraping:
1) Chrome Extension for Snooze & Schedule Email:-
Technology Stack: JavaScript, MVC Web API, Google OAuth to login
-> It is a Chrome Extension to send draft at a user-specified time based on their timezone. It is used for schedule email, snooze e-mail, Track e-mail. Also, there is one tool that is used for finding valid email address based on name and domain name.
-> Please find attached screenshots of my Chrome Extension.
2) Chrome Plugin for showing suggestion based on the stored data:-
-> Login with Auth0 account to use this plugin. If the plugin is enabled, at the time of page load it gets bind to every text area on your page and you will be able to do the following things.
-> For Ex: On Google, while you type something in the search box it shows suggestions. In this plugin, we show suggestion based on data which you stored.
Let's discuss the requirement in detail.
Thank you,
Rakesh
