Hello,
I'm writing this as a suggestion to any widget that is using a non text value. It would be nice to have the ability to change the formatting of field values to show as currency.
As my my current project, I'm using the "Near Me" widget with the sum operator to calculate parcels selected. Right now, the values are long data type and are displayed as such. It would be nice to be able to format the value into currency (like how you can do in ArcGIS Pro) to show a $ in front of the amount.
