Good Camera Protectors that won’t interfere with my Otterbox defender pro case?

Hello! I recently ordered those camera protectors from Amazon for my 15 pro but sadly they didn’t fit into the two cases I bought. Seems like they made the borders smaller and tighter so was wondering what camera protector will fit my Otterbox Defender Pro? Hopefully someone has experience thank you!

PS. I have a lens protector but want it to cover the glass where the flashlight and everything is seeing I work construction and it could scratch it. Thank you!
