Custom BI Connector - Create UI parameters dynamically

Dear all,

I'm developing a custom BI connector and I can show input parameters (e.g. date) in this here:

I do this via this code in M:

       let        

                dataFunction = (param1 as any, optional param2 as any) as table =>
                    GetData(actions, params, {param1, param2}, serverUrl),              

   
                typeParam = type function (
                    param1 as (type date meta [
                        Documentation.FieldCaption = "Start Date",
                        Documentation.FieldDescription = "Start of time range",
                        Documentation.SampleValues = {#date(2024, 1, 1)}
                    ]),
                    optional param2 as (type date meta [
                        Documentation.FieldCaption = "End Date",
                        Documentation.FieldDescription = "End of time range",
                        Documentation.SampleValues = {#date(2024, 12, 31)}
                    ])
                ) as table
         
            in
                Value.ReplaceType(dataFunction, typeParam)
