They're generally outboard and down below bumper line. So definitely side panels out... On the Proper Car, it's literally one Torx screw for the net clip and four push pins. Aka a two minute job whilst waiting for the kettle.
On the Jaaag, you probably need to remove the doors and rear seats.
It could also bee* the panel bond between the inner window aperture structure/roof cross member and the roof skin.
Does it buzz with the engine off? If not, then also consider the engine and gearbox mounts as it could be a contact transmission of vibration to the shell and, for the potential items I have suggested, may be exacerbated by a build quality/weakness at the back of the roof... The logic here being that the top of the glass is bonded to the roof skin and, in turn, the skin to the structure... A discrepancy in either bond will allow vibration/resonance. That noise is definitely a vibration or resonance rather than electrical, and whilst the cabin vents might be obstructed, that won't stop the movement that is allowing the vibration to occur. It may reduce the symptoms, but it won't cure the ailment.
Adding Dynamat or similar to the roof may also mitigate the sound.
*Terrible bee joke absolutely intended
