vSZ version: 6.1.2.0.487
I created an administrator called `apiuser` and added to a group called `WiFi API Group`. Of course, SUPER_ADMIN role is granted to that group(contains ALL domains):

By using this user's credential, I was able to login and call some APIs:
https://{host}:8443/wsg/api/public/query/zone
https://{host}:8443/wsg/api/public/query/ap
https://{host}:8443/wsg/api/public/query/client
https://{host}:8443/wsg/api/public/alert/event/list
However, the following API endpoints return 403 error saying "Lack of privilege":
https://{host}:8443/wsg/api/public/aps
https://{host}:8443/wsg/api/public/dhcpData/dhcpPools/{apMac}
Do I have to grant any other permission to the group?

This guy said that the group permission should be on the top-level system domain, but I cannot do that here:

If I click "System", all 4 domains are moved to right automatically.
Please help me!
However,
