Chrome extension development

Request details
I want a chrome extension developed that is based on Facebook automation.

And I already shared a video which is about the extension functions that I expect.

Here’s the video - https://www.youtube.com/watch?v=BC8Ep9UoYDA

In this video, 2 different Facebook chrome extensions are used. You can see the functionalities. The functionalities shown in this video are enough.

Extension names are
Friends connector pro
Elmessenger pro

(Available in Chrome Webstore)

The Only Main features that I need are

Creating tags and applying tags

Creating Welcome Message(Message segment) under each tag

Group and Post automation - Sending an automatic friend request. Followed by an auto welcome message

Canned responses or message templates - Under each tag

Messenger broadcasts - Send messages to people who are under any tag

Google calendar integration

I'm waiting for your response. Thank you.
