@tsentiloglou ,
* If you go to PowerApps dashboard or flow dashboard, you will see a menu option called solutions
* There you can create and manage your solutions
* Click on new solution
* Fill the form and select "CDS default publisher"
* Click on Add existing then Desktop flow
* Select your desktop flow
What are solutions?
* In simple words solution lets you package multiple PowerApps, cloud flows, desktop flows, dataverse tables etc. into one package. This will help you migrate your apps to different environments very easily
* In PowerApps you have 2 types of solutions. 1. Unmanaged solution 2. Managed solution
* Biggest difference between managed and unmanaged solutions is, unmanaged solution will let you do changes to your apps, flows, etc. after you deploy it to other environment. Where as managed solution will not let you do any changes to the apps, tables flows etc.
* Ideally when you're still in developing phase you will move solution as unmanaged
* After completing the development, you can move the solution as managed to the production environment. This will stop people from making any changes to the apps, flows etc. in production environment.
If you want to know more about the solutions, here is the link:
