Split keyboard on iPhone 12 Pro Max?

I am using an iPhone 12 Pro Max and like the title says, I am curious if there is a way to use a split keyboard when the phone is in landscape mode. I have decently sized hands but when the phone is in lansdscape mode it is a bit difficult to reach keys towards the center of the keyboard. I have looked everywhere I can and searched online but can’t seem to find anything for the iPhone, just iPad. It seems odd that this wouldn’t be something that they would include, in my research apparently older versions of iOS would let you use a split keyboard on your phone, not to mention you would have to have hulk hands to not feel uncomfortable typing in landscape. Any recommendations, advice or information would be greatly appreciated. I am using iOS 15 btw.
