​Small clear plastic piece found at bottom of dishwasher

I recently found this small clear plastic piece about 1.5 inches in length at the bottom of my dishwasher after running it. For the life of me, I can’t figure out where it came from. I tried looking inside the dishwasher to see if it’s a part that came loose, but I couldn’t find anything.

Here’s some additional context: – I live in an apartment. This dishwasher isn’t new. – I cleaned the dishwasher filter just a couple weeks ago, so I know this little piece wasn’t in there before. – My dishwasher is a GE.

If anyone has ideas about what this thing is, I’d appreciate it!
