Spare parts?

Hi all, recently purchased a stoic 4. Beautiful bike, painful setup.

Hoping for some guidance. The bike required a bit more setup than the guides or videos alluded to, but got through it I think. There were a few small pieces at the bottom of the box that weren’t depicted on any parts list or instructions I was able to find.

Hoping someone has the bike that may be able to identify and point me in the right direction or if they are even needed.

Thanks in advance for any help!
