Microsoft now has implemented "compare with Bing chat" button when you visit Google Bard in Edge ( reddthat.com )

When you visit the Google's chatbot bard's website in Microsoft Bing. A New Button pops up besides the search bar which lets you compare bard results with Bing chat's.
I have no idea why they implemented this, well maybe to show off the their chatbot is better than bard or something?
