How to use regex in filter filterCriterion

Content

Hello Experts,

I have a webservice endpoint which has some filterCriterion defined to restrict the data. The filters look like:

"variables": {
    "getServiceDataProvider": {
      "type": "vb/ServiceDataProvider",
      "defaultValue": {
        "endpoint": "serviceRequests/getServiceRequests",
        "idAttribute": "SrId",
        "itemsPath": "items",
        "responseType": "flow:getServiceRequestsResponse",
        "filterCriterion": {
          "op": "$and",
          "criteria": [{
            "attribute": "{{ \"col1\" }}",
            "op": "{{ \"$eq\" }}",
            "value": "{{$page.variables.var1}}"
          },
          {
            "attribute": "{{ \"col2\" }}",
            "op": "{{ \"$eq\" }}",
            "value": "{{$page.variables.var2}}"
          }]
        }
    }

Now one of these filter columns needs to have some multiple static strings in the filter criteria to be searched with some "in" clause like:

 {
            "attribute": "{{ \"StatusCd\" }}",
            "op": "{{ \"in\" }}",
            "value": "{{\"SVC_PENDING_RESOURCING\", \"SVC_PENDING_DELIVERY\"}}"
