Is Company Portal App required for Device Enrolled iPad (Kiosk scenario)

Thanks guys for the reply. I actually found the answer from Microsoft Docs. Basically you don't use Company Portal App for devices that are enrolled with no user affinity, such as Kiosk devices.

Devices that are configured with no user affinity do not support the Company Portal and should not have the app installed. The Company Portal is designed for users who have corporate credentials and require access to personalized corporate resources (like email). Devices that are enrolled with no user affinity aren't intended to have a dedicated user sign in. Kiosk, point of sale (POS), or shared-utility devices are typical use cases for devices that are enrolled with no user affinity.
