What is the use of the 'Disable Help Center' button?

In the Configuration process, you can make the Help Center inaccessible by clicking the Disable Help Center button. Your readers will see a ‘Coming Soon’ message if they open the Help Center after it is disabled. 
After you make all the changes, you can click the Enable Help Center button to make the Help Center accessible to your customers again.
