User group permissions at once

Hi,

In any services related to user permissions, how to add multiple inputs like multiple groups or multiple entities in single service at once. eg:

Things["ThingName"].AddRunTimePermission({
principal: "CM_Administrators_group" /* STRING */,    //here if I need to add multiple groups
allow: true /* BOOLEAN */,
resource: "*" /* STRING */,
type: "PropertyRead" /* STRING */,    //here if I need to add multiple types
principalType: "Group" /* STRING */
});

Regards,
