How to use the aria-query.roles.keys function in aria-query

"VStartTag" (node) {
        const element = node.parent;
        const type = utils.getElementType(element);
        const role = utils.getRoleValue(element)
        if (!role) {
          return
        }
        if (!dom.get(type)) {
          return;
        }
        const normalizedRoles = String(role).toLowerCase().split(' ');
        const roleArray = [...roles.keys()];
        const validRoles = normalizedRoles.filter(value => roleArray.indexOf(value) >  -1)
        validRoles.forEach((role) => {
          const { requiredProps: requiredPropKeyValues } = roles.get(role);
          const requiredProps = Object.keys(requiredPropKeyValues);

          if (requiredProps.length > 0) {
            const hasRequiredProps = requiredProps.every(prop => utils.getAttribute(element, prop) !== undefined)
            if (!hasRequiredProps) {
              context.report({
                node,
                message: errorMessage(role.toLowerCase(), requiredProps),
              });
            }
          }
        })
      }

        const validRoles = [...roles.keys()].filter(role => roles.get(role).abstract === false);
        const isValid = normalizedValues.every(val => validRoles.indexOf(val) > -1);
