Behavior

        @Override
        public void enter(InputEvent event, float x, float y, int pointer, Actor fromActor) {
            button.addAction(Actions.parallel(
                    Actions.moveBy(0, 5, 0.1f),
                    Actions.scaleTo(1.05f, 1.05f, 0.1f)
            ));
            //logger.info("Hover feature activated"); uncomment this if you want to check hover feature

        public void exit(InputEvent event, float x, float y, int pointer, Actor toActor) {
            button.addAction(Actions.parallel(
                    Actions.moveBy(0, -5, 0.1f),
                    Actions.scaleTo(1f, 1f, 0.1f)
