Trying to set autoremove to yes on robot in Nimbus with Nimbus API and C#

I have tried something like this - using C# and the Nimbus APU fro, NimbusAPI.dll:

NimbusSession contSession = new NimbusSession("localhost", (int)NimbusPort.Controller);
contSession.Login("user", "password", true);
ControllerConfig conTest = new ControllerConfig("controller", contSession);
conTest.SetValue("controller", "autoremove", "yes");
conTest.Save();

Select allOpen in new window

But here I am not able to choose what robot to do the changes for. The first argument on method SetValue is "Section," where do I find this?

How am I able to set the raw configuration "autoremove" to "yes" on a robots control probe?
