Add coconut aminos, honey, vinegar, ginger, garlic powder, salt, and red pepper flakes to a bowl and whisk to combine.
Place trivet inside your Instant Pot and pile the chicken pieces on top of it.
Pour the coconut amino mixture over the chicken as you add it to the pot.
Place the lid on and set the valve to the “sealing” position.
Set the pressure cooker setting to high pressure for 10 minutes.
While the chicken it cooking, it’s time to make your arrowroot slurry. Add 4 tablespoons of arrowroot powder and 3 tablespoons of water to a cup and stir with a fork until the mixture becomes runny. Set it aside for later.
Once the timer goes off, wait a minute or so and then do a quick release. I recommend using a long-handled spoon to move the valve so that your hand stays far away from the hot steam that will stream out. When the float valve drops, carefully unlock and remove the lid.
While wearing oven mitts, lift the trivet up and hold it at angle while scooping the chicken back into the pot.
Set the Instant Pot to the sauté setting, then give the arrowroot slurry a good stir and pour it in. Stir the mixture occasionally until it has thicken- it should take a few minutes or less - then turn off the Instant Pot and serve.
