I checked some extra (replacement) knobs that I have in my collection.
The all have the metal insert already inside. I was able to remove one
of the inserts with a small screwdriver - there are three slots in the
rounded part of the insert, and I was able to pull it out by placing
the tip of the screwdriver there and pulling - then collecting it from
the floor under my bench :) Reinserting was very easy, with
needle-noise pliers. Obviously the flat side needs to be aligned when
inserting.

If yours doesn't insert easily, you may have a defective knob (or insert)
