How to fully implement Commands using the OperationalState::Delegate

[tomasmcguinness]

I am trying to implement a DishWasher device type.

I have been struggling with the OperationalState::Delegate

So far, I have implemented my own Delegate:

class OperationalStateDelegate : public Delegate

and successfully answered chip-tool operationalstate read phase-list and chip-tool operationalstate read operational-state-list

However, when I attempt to send a command like:

chip-tool operationalstate start 0x05 0x01

I get this error, indicate the commands aren't supported

I am expecting, in this case, for the HandleStartStateCallback method to be invoked, but that doesn't happen.

Can anyone steer me in the right direction?
