iMessages storage in iCloud

I am trying to make sure I do not run out of iCloud storage and looked and saw I have 48GB of messages stored in iCloud.

As a videographer, I know most of this storage is probably videos I sent over text so it can be deleted. But when I try to review large attachments, only the ones stored on my device show up (2-3 GB on iPhone and 10GB on Mac).

Is there a way to see everything individually stored in iCloud and individually delete messages and attachments from there to free up storage in the cloud?
