At the top of all knowledge base articles, costumers can click on Help Center and go to the Help center main page where they can open the service desks to raise tickets, or use the search bar to look for the articles back on the knowledge bases.
However, I couldn't add a direct link to the main page of the knowledge base.
By customizing the help center I can only change banner, color, logo and texts.
Is there a ways to add links to knowledge bases?
