How can I add a filter(Countofvehicles]10) for aggregate field for below code?

/*fetch the data group by colour and for each colour how many vechicles
 are there in that record type*/
 
 
a!queryRecordType(
  recordtype:recordType!AA Vehicle,
  fields:a!aggregationFields(
    groupings: {
      a!grouping(
        field:recordType!AA Vehicle.fields.color,
        alias:"color"
      )
    },
    
    measures: {
      a!measure(
        field:'recordType!AA Vehicle.fields.vehicleId',
        function:"COUNT",
        alias:"countofvehicles"
      )
    }
  ),
  pagingInfo: a!pagingInfo(
    startIndex: 1,
    batchSize: 100,
    sort: a!sortInfo(
      field:"countofvehicles"
    )  
  )
)
