I don't know if it is the Original Equipment Manufacturer but it does match the OEM part exactly and works very well.

Andersen Hinged Door Lock Actuator

Q: what part is connected to this called? cant find the white knob thing ?

Wish I had a better answer 😐 It is called a thumb knob but you will not find it as individual part it is sold mounted to the faceplate as is the opening handle. I would suggest going to your local Re-Store/Habitat to hopefully find a used one, a new faceplate is around $200 from Anderson.

Q: Is this one piece or two. When I inspect mine, the inch-long rectangular cylinder part comes out. Does that mean it is broken?

It is broken. return it for another one. The two pieces are supposed to be joined together from the factory. I'm a locksmith. I purchased one to replace a part that had separated on a customers door

Q: Is this the part that springs the handle back in place when latching the 3 point lock. Right now my handle just sags but still locks.

No, this piece actually locks the turning knob. My knob kept turning and wouldn’t latch to lock. This fixed that issue.
