## Team Members Management
* Public datasets are available to all users and do not take up team storage space.
*
```
Private datasets can only be accessed by inviting team members to join. After members join the collaboration, they can operate on the dataset on different levels according to their corresponding permissions (Viewer, User, Editor, Admin).
```
* By default, the Super Admin has all the Admin permissions on team datasets.
###
**Dataset Permission Types**

**Previewer**
```
The default permission for team members on all the datasets within the team. You can preview data and view the details page of the team's private datasets but cannot view the data list and version records.
* **Viewer**
Besides Previewer permission, you can also view the data list and version records.
* **User**
