Squeaky clutch

Newbie here. Just purchased a 1998 Z3 roadster and was trying to resolve a squeaky clutch noise. I think it is coming from near the trany when I push in the clutch pedal. Any ideas on how/if you can lube this to get the squeaking out?
Thanks in advance!

If the pedal is stiff and the squeak is from under the dash, it would be the clutch pedal bushing.
I bought both the plastic and the bronze and prefer the bronze:

Access is hard, especially if the seat is not removed. There several DIYs:

Well this weekend I replaced the seat bushings and while I had the seats out I did the clutch pedal bushing too. The clutch bushings that were in there looked new. I still have the squeak when I push in and as I release off the pedal and it only occurs during the actual movement of the pedal. With my head under the dash and near the pedals it still sounds like the noise is on the other side of the firewall. Again, the noise is during depression and release of the clutch pedal and you hear it both when the engine is running or engine off. This is my last squeak to fix!
Where could I look next?

Parts list shows a input cylinder clutch (inside) and an output cylinder clutch in the engine compartment. Could it be that the clutch needs to be bled?

... I just saw another posting video and I think that the issues are pointed out there. so that is my next step...
What a great find:
... Put the car up on ramps, then remove the clutch slave cylinder slowly and prop it on the frame somewhere.
You can put several fingers into the bell housing and move the clutch actuating lever back and forth.
Now making sure that the lever is fully forward, take the spray lithium grease with a spray tube attached, put the tube into the bell housing hole and angle it toward the throw out bearing. spray liberally as you move the spray tube all around...

Who'd have thought the throw out bearing could squeak.

There is a clutch-fork pivot inside the bell housing of the transmission. The original pivot was nylon, but sometimes people replace them with steel ones. They can squeak. I suspect this is what has happened to your car. I really don't think there is a way to fix that without removing the transmission and either lubricating the pivot or replacing it with a nylon one.
