you probably need to type into an element contained within the the body element.
The body tag is part of the standard definition of an HTML Page:
It's not a real element per se - it's a container.
It's true that we record clicks on HTML body elements but not typing. However, I don't think there's an actual need to do that. Please recheck whether it's the actual body element that you need to type into or you're typing into something contained within the body tag. Please give me some additional details on your use case.
All the best,
