@DO-Sys, Thanks for posting Q&A.
We can package apps to .intunewin using Microsoft Win32 Content Prep Tool and upload them to Intune then deploy them. In Assignment session, please assign to Available for enrolled devices, after that users can install the app from the company portal app.

Please note that when the app was deployed via Intune, it will install successfully without user interaction by simply clicking on install in company portal.
Hope it will help.
