Add the chicken with all the marinade juices and the chicken broth to the Instant Pot. Cover, seal the pressure valve, and cook on high manual pressure for 10 minutes, then let the pressure release naturally for 5 minutes, then carefully release the pressure manually by using the quick-release valve.
