Squeaky belt - diagnose ?

Just bought a '12 Civic a week ago for the kids and while driving it the other day (with the radio off, windows up), I can hear what sounds like a mouse squeaking when the engine is around 1500 rpm. The sound very much appears to be coming from the passenger side (where the belt is). As RPMs increase, it goes away. Can't say if it happens at higher RPMs since it's not loud. I have the CarFax and it's had a good amount of maintenance at local shops as well as Honda dealers, but no record of the serpentine belt having been changed. Visually, it looks real good (on the ribbed side) but since I don't know, I'll change it soon.

It does appear that Civics or the 1.8L engine has a common issue with the belt tensioner making "noise" but a lot of those reports describe it as a rattle more than squeaking. I suppose the next step is change the belt and see if it goes away... 🤷‍♂️ Is what I describe indicative of a belt vs a pulley vs the tensioner though ? Or something else ?

Thanks in advance

It could just be how the engine sounds.
