UiPath Apps Utilization in Real Time Scenario

Hey Guys,
Wanted to understand how we can use UiPath Apps in a real time scenario while considering the cost of licensing and vdi provisioning, how much feasible it would be to integrate it with ongoing automations?
Is it necessary to provision an unattended licensed VDI separately for UiPath Apps or something else can be planned to reduce cost and increase features of automation.

Looking forward to answers
Thank You
