Remove "I am not a robot" notification

How do I remove the "I am not a robot" notification?

I modified the instructions for how to remove the "I Am Not A Robot" extension

Safari

1. Open Safari.
2. Click Safari (upper left of screen next to apple) > Preferences > WEBSITES.
3. In the sidebar, identify the Robotics extension, select Deny then highlight the extension and click Uninstall.
4. I also unchecked “Allow websites to ask for permission to send notifications.” 

I hope this helps.
