See this recipe – requires both microwave and air fryer. If you just have an air fryer then I would say around 45 mins at maximum temperature, wrap it in foil first.
To crisp the skin it has to be unwrapped from the foil. You can do this for the last 10 minutes or so. Take it out of the fryer, unwrap it, spray it with a bit of PAM and then put it back in.
