How to acces "forward direction" field from the RemoteControl

Hi folks,
Noob programmer here.
Tryed my best and searched a lot, but couldn't figure out, how to manipulate the "forward direction" dropdown from the RemoteControl block.
here 2 "solutions" that didnt work out:

void Main(string argument)
{
IMyRemoteControl test = GridTerminalSystem.GetBlockWithName("test") as IMyRemoteControl;
test.GetActionWithName("Up").Apply(test);
test.ApplyAction("Up");
}

no errors thrown, the autpilot simply ignores this action and doesnt change the dropdown...
