Where is the CLOUD tab?
The CLOUD tab becomes visible only when an on-premise gateway is created. If no on-premise gateway exists, Unattended Access will use the managed service option, which is enabled by default and requires no configuration.
Configuring an on-premise gateway means disabling the cloud gateway (see How do I setup a Self-hosted Implementation?) which is why the CLOUD tab becomes available when a gateway is created.
