Hide unpublished content from other editors

Hi

We will publish financial information on our site but have the need to hide it from all editors but one while working on it.

Due to financial regulations the information can´t be shown even internally(insider trading) so we have to hide it somehow while working on it.

I looked att solving it thru Folder/Content-item permissions but that only work as a Whitelist and then I would have have to add all folders to all roles except the Financial folder.

We are new to Storyblok so we might have missed something(hopefully)

Best regards
