Again, mostly guesswork and looking at pictures but it looks like there is a countersunk recess on the inside face of the clutch lifter plate (17) which I'm guessing is where that o-ring goes. I'd imagine the clutch screw (11) goes down through the middle of all the clutch lifter parts and protrudes slightly with the o-ring over the end of it.

See if that all fits. It's where it's shown on the exploded diagram so if it fits neatly in the recess on the clutch lifter plate and over the plain end of the clutch screw, I'd say it's a shoe-in.

I think its function is to stop oil creeping along the threads between the clutch lifter plate and the clutch screw and finding its way to the outside of the bike along that screw. Pic below of the recess in the lifter plate I'd guess it goes in.

If you don't have one, it can't happen and you don't need it.
