"About" button on silence is not working

Expected behavior

I expected that clicking on the "about" button will bring up some information about the application or lead to a web page, just like the way "privacy policy" button does.

Actual behavior

The "about" button is not functional, it does nothing after clicking on it

How to reproduce

1. Download silence app from F-driod
2. Launch the application
3. Click on the three dotted menu at the top right of application
4. Go to settings. At the bottom, click on about. It does nothing.
