Access Status Reason Parameter in Plugin on setStateDynamicEntity Message

I am working with booking transactions where I have multiple status

I am using statecode and statuscode to accomplish it

The plugin is triggered on Activate and Deactivate Record

But I am unable to access the Status Reason selected for Activation or Deactivation

My further processing is dependent on status reason received

here is the code sample I am using for plugin

 if (context.InputParameters.Contains("EntityMoniker") &&
                context.InputParameters["EntityMoniker"] is EntityReference)
            {
                
                EntityReference entity = (EntityReference)context.InputParameters["EntityMoniker"];
                var state = (OptionSetValue)context.InputParameters["State"];
                var status = (OptionSetValue)context.InputParameters["Status"];
                

                if (entity.LogicalName != "psm_quote")
                    return;

               // code for further processing

            }

While debugging I am getting state Value as 0

and status value as -1

please guide me how to get selected value of status reason

Thanks in advance
