If you collaborate with a client you might want to keep some of your posts that are still a work in progress away from their feed. You can simply save your posts as private to your team, and choose to make them visible whenever they are ready for approval. To do so, in your composer, click on the “eye” icon. 

To enable this feature, you need to have at least one person assigned as a client or external member in your workspace. Internal posts are marked with a striped top bar and crossed eye icon.

None of your clients will be able to see the post unless you unhide it by clicking the crossed eye icon.

From your workspace settings, choose the default visibility of posts when you create them.
