What will be the arguments required in a payload to be posted for performing a scheduleMaintenance action on a Router using EDAA?

I am trying to perform an action schedule maintenance which is allowed as per EDAA programmer guide. It is mentioned POST operation is required and hence we have to have a payload with required arguments. The ideal way to get the list of arguments is to use dmctl and getOperations on that particular Class which returns a list of operations along with their arguments. However, I could not find the scheduleMaintenance operation for a Router Class on SAM, and hence not sure what arguments are needed for the payload.

Has anyone tried implementing this action or if you could provide the information on which arguments will be needed, it will be of great help? I presume most probably StartTime, EndTime etc. may be needed however I am not sure about the exact argument names.
