@Chidananda, M A, Thanks for posting in Q&A. Based as I know, only Android work profile for personal devices and Android device administrator enrolled devices are using Company portal. For other Android Enterprise enrollment methods, they use Microsoft Intune app.

And if the end user attempts to launch the Intune Company Portal app, the end user will be redirected to the Microsoft Intune app and the Company Portal app icon will be subsequently hidden. For other Android enterprise enrollment devices, please use Microsoft Intune app instead.
