Could you please tell me how GUI dashboard is controlled in case of MCX?

Our partner configured MCX with 3 x AP-6532.

AP-6532- was configured as Root and connected to the wired.

AP-6532- and were configured as Non-Root.

In this environment, they can access to GUI Dashboard through AP-6532-.

Is this the expected behavior?

If so, what will be the rule?  (In which AP would display at Dashboard?) This partner wanted to see through AP-6532- if this is the specification…

Your side clarification would be greatly appreciated.

Thanks in advance
