Separate multiple select responses in serial chart

[BNix_TPA]

Hi! I found an example of some code to separate multi-select responses into separate records from the Esri Github.  The code works great, except I need a few additional values added to the array so I can further filter the data using other widgets within the dashboard.  Where would I add these additional fields?  The fields are "date_time & type_of_activity".

// Reference layer using the FeatureSetByPortalItem() method.

var portal = Portal('https://www.arcgis.com')

var fs = FeatureSetByPortalItem(

    portal,

    'c68e6ea9b6b74c30bc94ef901d34f5f2',

    0,

    ['focus_area'],

    false

);

// Create empty array for features and feat object

var features = [];

var feat;

// Split comma separated hazard types and store in dictionary.  

for (var feature in fs) {

    var split_array  =  Split(feature["focus_area"], ',')

    var count_arr = Count(split_array)

    for(var i = 0; i < count_arr; i++ ){

        feat = {

            'attributes': {

                'split_choices': Trim(split_array[i])

            }

        }

        Push(features, feat);

}}

// Empty dictionary to capture each hazard reported as separate rows.

var choicesDict = {

    'fields': [

        { 'name': 'split_choices', 'type': 'esriFieldTypeString'}],

    'geometryType': '',

    'features': features

};

// Convert dictionary to featureSet.

var fs_dict = FeatureSet(Text(choicesDict));

// Return featureset after grouping by hazard types.

return GroupBy(fs_dict, ['split_choices'],

       [{ name: 'split_count', expression: 'split_choices', statistic: 'COUNT' }]);
