Unity does not appear as a full screen in 3rd party application

197859-untitled.jpgGood day dears, We are trying to run the Unity exe inside a 3rd party application running in a full screen mode, and we have a problem that this 3rd party app is able to start the Unity exe but in the background only, while it should display the Unity exe inside a specific area designed to display the Unity.

I tried several methods and it didn’t work, may anyone help?
