Adding a "About Us" function

[sharur7]

Is your feature request related to a problem? Please describe.
It would be great if we have a function that will direct us to the about us page.

Describe the solution you'd like
I have tried doing the about us function by creating an icon in the corner of the pop-up that will direct users to the About Us page of scrroll-in. The About Us page contains some description, version of our extension, Github link for contributions, and twitter link for any doubts.

Additional context
I implemented the idea and came up with something like this:
