     .setEntityId("entityId")
     .setPermissions(new RolePermissions().setReadPermission(true));
 List<PathAccessControlEntry> pathAccessControlEntries = new ArrayList<>();
 pathAccessControlEntries.add(pathAccessControlEntry);

 client.updateAccessControlRecursive(pathAccessControlEntries).subscribe(
