You can find the device by navigating to Deployments: Core Identities > Chromebook Users. You can also find the serial number on the back of the device itself.

When a Chromebook in public session mode is registered with Umbrella, DNS queries from the device appear in Activity Search.

To create a policy specific to public session mode, navigate to Policies > Management > All Policies and select Chromebooks.
