Win32 applications are not appearing in the company portal

Hello, I am new to Intune and am experiencing an issue with Win32 apps not appearing in the company portal application.

I can upload line-of-business apps and these apps do appear the company portal application and I can install them successfully. However, I seem to be missing something when uploading Win32 apps. 

To clarify, the Win32 application's Assignment is set under "Available for all enrolled devices" to a group that contains the Intune user who is logged in to the company portal. 

Any ideas why I can upload LOB apps to the company portal but not Win32? 

Thanks
