How to use the @leafygreen-ui/lib.keyMap.Enter function in @leafygreen-ui/lib

if (!e.shiftKey && trapLastMenuItem(filteredRefs)) {
          e.preventDefault();
          setFocused(refs[0]);
          refs[0].focus();
        }

        if (e.shiftKey && trapFirstMenuItem()) {
          e.preventDefault();
          filteredRefs[filteredRefs.length - 1].focus();
          setFocused(filteredRefs[filteredRefs.length - 1]);
        }

        break;

      case keyMap.Space:
      case keyMap.Enter:
        if (!open) {
          setFocused(refs[0]);
          refs[0].focus();
        }
        break;
    }
  }
