Default Rattling noise in engine bay - Mazda CX5

Hi,
I have a 2018 Mazda CX-5 Touring (45,000 miles) that often develops a strange rattling noise when engine is on (cold or warm). It seems to come from the front of the right side of the engine bay (when facing the engine). Any idea of what this could be? Thank you.
I can send you a 20'' recording of the noise (my file exceeds the limit of the forum).

I'd check all the pulleys for sure.
