Xbox 360 Elite Eject Button Not Pressable

I bought this from someone on offer up because it would not read discs. I opened it up and it was very dusty and luckily alcohol on the laser fixed it - anyways I’ve never opened up an Xbox 360 before and I noticed this metal piece/clip? Came off once I removed the eject button. I kept it around and not sure if this is why the eject button won’t click or is not pressable. I have attached some photos as well.

If I press the long arm underneath the eject button it will press and make the click noise to eject the disc but if I press the button itself it does not click, just stays firmly there. I am not sure if the reason is that little clip might be missing somewhere there but I can’t find anything online or on YouTube about this. To my knowledge this is the Xbox 360 Elite.

Lastly, I did make sure the green piece (pictured) is firmly in place where it belongs and so is the eject button. If anyone has any insight or helpful information I would appreciate it.
