Managing apps and software deployment through Microsoft Intune
@Aravinth Mathan , Maybe we can consider to select the assignment type as "Available for enrolled device". For this type, users can install the app from company portal when they log in.
If we just want to notify the end user, we can configure "End user notification" as "Show all toast notifications". In addition, we can also consider to configure the start time and deadline time for a Win32 app. We can see more details in the following link:

Hope it can help.
