Let Domain User Manage RemoteApp connection

Hello, 

I have a client who needs to disconnect/log out domain users from the Server. We are using the RemoteApp on our Windows Server 2012 R2. This server is only meant for the RemoteApp. I need to give her permission to only let her manage the remote connection. I had searched the internet but i don't get my answer. 

Any chance of doing it? Please let me know. 

Thanks.
