Turn the Instapot off

Cover the pot and secure the lid. Make sure the valve is set to sealing. Set the pressure cook button to 4 minutes and start it

When the time is up, move the valve to venting. Remove the lid and quickly top the chicken with both of the cheeses

Place the lid back on the Instapot and close it. Do not turn the Instapot back on, just leave it on warm (or off, it does not matter), to allow the cheese to melt. Leave the lid on for about 4 minutes
