@jhauan Thanks for posting in our Q&A.
From your description, other apps will stay front and only open .ica files through Citrix Workspace App will get minimized in the background. Did this situation occur in a device without enrollment and without kiosk mode? Based on my understanding, there is no such setting to making apps stay front in the kiosk profile.
Given this situation, it is suggested to contact Citrix support to consult if it is caused by the app itself.
