How do I view an old iCloud update?

Hello,

A long time ago, I deleted an messages conversation on my iPad mini(the original one). It is not urgent that I get the information back, I wanted to know if it would be possible for me to see the conversation, since they were backed up in an automatic iCloud update. I don't want to wipe my device and re-download the information. I would also not like to use any 3rd party apps. I know it's a tall order, and may not be possible, but I'd appreciate any help.

Thanks!
