 **Enabling recording anonymization on upload:**<br>
 Anonymizing recording on upload requires an Anonymization Add-on. If you have registered an Anonymization Add-on and linked a device to it you can you create a new workspace and enable `Face Blurring`. Any recording uploaded to this workspace will be anonymized.

+## Sharing Add-on Benefits
+
+### Workspace Management
+
+You can create multiple workspaces within the user account registered with an add-on. This allows you to share the benefits of your add-on with other users without them needing to purchase their own add-ons.
+
+### Inviting Users
+
+You can invite other users to [join your workspaces](https://docs.pupil-labs.com/neon/pupil-cloud/workspaces/). As part of your workspaces, invited users can, for example, view, edit, enrich, and download recordings based on the role assigned to them.
+
+### Device Access
+
+Other users can also log into the [Companion App](https://docs.pupil-labs.com/neon/data-collection/ecosystem-overview/#neon-companion-app) on the device linked to your add-on using their own accounts. They can then upload recordings to your workspaces, thereby benefiting from the add-on features.
