Loud Clicking Sound from under hood

Greetings fellow friends of the Prius!

I am the happy owner of a 2016 Prius Four Touring and unfortunately for the last few days this loud clicking noise has been interrupting my joyrides. The sound is coming from an area under the hood and behind the glove compartment. Any idea what it might be? I hear the sound usually shortly after I park the car and the engine turns off or shortly after the engine turns on (when it switches from EV mode to hybrid).

Here is the link to the video with the sound:
