Can i remove Inputs and Actions from a java FXGL game

Question

We are using FXGL to programm a little game. At the beginning we initialized a few UserActions with KeyCodes for inputs. But later this UserActions shall get deleted/removed.

I found the possibility to rebind an action to a new the KeyCode. But i can't figure out, how to remove this action.

This is what i found and use actually to rebind the Action EXIT_GAME from KeyCode.D to KeyCode.L:

public static void initializeGameInputs(){ 
        //Todo delete this workaround for waiting time - otherwise game crashes
        getInput().mockKeyRelease(KeyCode.G);
        getInput().mockKeyRelease(KeyCode.H);
    

        getInput().rebind(getInput().getActionByName(EXIT_GAME), KeyCode.L);
        getInput().rebind(getInput().getActionByName(START_GAME), KeyCode.K);
    
        getInput().addAction(new WalkUserAction(), KeyCode.D, VirtualButton.RIGHT);
        getInput().addAction(new WalkLeftUserAction(), KeyCode.A, VirtualButton.LEFT);
        getInput().addAction(new JumpUserAction(), KeyCode.W, VirtualButton.UP);
    }

But i want to delete this action. Thank you a lot for your help!
