Google appears to be testing a new WhatsApp button within Local Results. This was new to me — I hadn’t seen a WhatsApp button in Google Local Results before, and I couldn’t find any other reports of this. When I checked again a day later, I wasn’t able to see the button anymore.
Here is a screenshot of this.

I was testing this in Incognito mode, so I wasn’t able to fully verify the behavior, but I’m assuming clicking the button would let users start a chat with that particular business directly on WhatsApp.
