Broken handle

A home owner from Hawaii says:

Has made in New Zealand, no other identifying info.. Believe it's Pella. Broken handle is the non-locking one, just pulls a 4' glass slider.

Took it apart to show the small broken cylindric part on the photos below. No idea what held it in place as I don't see threading in the remaining cylinder.

Sent a photo months ago... A previous inquiry for window latch replacement was handled almost instantly. Am hoping you can help, would rather not have to replace both handles as the locking one works.

Looking forward to hearing from you.
Aloha,
Louise
