I couldn't find where to click in order to replace the current version with a snapshot

The share icon was really not where I'd had thought to click in order to replace the current version with the snapshot version.
I actually thought it was not possible until a colleague told me where to click.
Maybe replace the share icon with arrow down icon so users can understand a drop menu will appear with actions related to the snapshot. I just thought it was a button to share my snapshot.
