Don't end RemoteApp session on window close?

Question

RDP

I'm poking around in terminal services, the idea arose to control game servers via rdp. The problem is this: if you start the application and then close it, it really closes, i.e. at all. And I would like to close the window with the ability to connect back. And if you run the application again, the old session does not fall off, a new one starts.
Windows Server 2012 R2
Apparently this feature has a specific name, so I couldn't google it, please help!

Answer 1

The RApp\rdweb session settings have everything you need to do this.

Answer 2

no it's not that. Namely, if you manually close the window with the connection, the application itself closes. And I would like to be able to return to the application.
