Document Version Control


I am having an issue when trying to compare document versions in nextcloud. I do not want to use the “Restore” button as that replaces the document in question, but rather restore a duplicate so people can compare the differences and choose which version they actually want to restore. I am sure I am just missing something as this is a simple option. Can someone point me in the right direction or tell me what I may be missing?

Nextcloud Version: 15.04
