Can I play overwatch with a keyboard and mouse on Xbox?

After some reading on various forums, it seems that despite Blizzard having previously stated that they are not in favor the idea of KB+M on console, there seems to be plenty of videos on youtube showing that there are in fact players using KBM through the use of 3rd party adapters.

In other words, while Overwatch on Xbox appears to be KBM-compatible through the use of 3rd party tools, it seems unclear whether it's oficially allowed. Just make sure you actually skim through the documents and see if it's cheating before clicking "I agree".
