To switch between a workspace and a private project, follow the below steps:
- Click on the three-dot of the project
- Select "Project details"
- Toggle on "Make private" to switch the project from a workspace project to a private project or vice versa.
Note 1: Only the project owner, which is the person who created the project by default, has the control to switch the project permission.
Note 2: When a project is switched from workspace to private, nobody in the project will yet lose access to the project. However, you can remove them manually.
