While incredibly powerful and useful, the Custom App feature is limited since it requires manual interaction in a GUI to create and update applications. This becomes much more burdensome the more custom apps you have. What I would like to see once Custom Apps is more mature is an API or PowerShell module that allows an administrator to automate creating/updating custom apps.
For instance, if my Dev team provides me with new installers for an internal application, it would make my life a lot easier if I could run a script or command that interacts with the cloud portal and provides the new installer file and updates all the relevant application information. Or even if I could create a Power Automate flow that looks for content added in a SharePoint document library which automatically interacts with the cloud portal to update applications.
Any update on this? I am looking for an API, but there is none?
