Vegan buttermilk: In case you are vegan,  you can make your own vegan buttermilk. Just use 1 cup of plant-based milk like soy milk or almond milk. You can try making your own almond milk like this. Add 1 tbsp. of lemon juice and keep it aside for 10 minutes. You can use the slightly curdled milk as the vegan buttermilk.
If you have smaller mushroom, your Air frying time will vary a bit, so keep a watch.
