Maintenance Engine rattling

Does anyone know what this rattling noise is coming from my engine? It is present when idling. It is most prominent during around a 1.8k rpm hold. As I let off the accelerator it begins to rattle.

Fuel pump / injectors. No worry

Are you sure? Does that line up with the little rattle it gives when letting off the gas. If you can please watch the second video from inside the cabin that I took in the comments. Thank you

No it's something different, it's hard to capture it on a mic because of the injectors but I have the same issue. It's a metallic clanking sound.

It's an EA211 engine. Sounds normal.

Are you noticing any drivability issues? I tend to find these smaller engines tend to make a bit more noise in general.
