Add the coconut aminos to the Instant Pot on saute mode and cook for 5-8 minutes, until thickened and reduced by half, then turn off the Instant Pot.
Stir in the lime juice, sriracha, garlic powder, ginger, pineapple juice, and sesame oil. Add the chicken and toss to coat, then set the Instant Pot to 'manual' and adjust to cook for 12 minutes.
While the chicken cooks, make the pineapple salsa. Add all of the salsa ingredients to a bowl and toss to coat, then set aside.
When the timer on the Instant Pot goes off, manually release the pressure, then remove the chicken from the pot and shred with two forks, or with the paddle attachment of your stand mixer.
Put the Instant Pot back on 'saute' mode, then whisk the arrowroot starch with 1/4 cup water. Pour the arrowroot mixture into the sauce and whisk to combine. Let the sauce come to a boil and thicken, then turn off the Instant Pot and return the chicken to the pot and toss it to coat with the sauce.
Assemble the bowls with the rice, chicken, and pineapple salsa and enjoy!
