Feedback mechanism on contextual help

In order to understand if contextual help is really helpful or needs an update

When I open contextual help and scroll to the bottom, I can see a question and 2 buttons:
Did this help?
Yes - No
Clicking a button

• sends an event to google analytics (category maps to existing categories, event: name of the property, label: help message, value: 1 or 0)
• hides buttons and shows user a message: "thank you for your feedback"
