Investigation

Date field by default uses defaultOperator configured.

• So for this custom operator support, add a type for date, something like this to include isNull.

 case "date": {
     return [...this.props.defaultOperators, "isNull"];
 }

• Filter conversion on payload is already available for this operator. So no extra step required for this.
• The field value should be disabled when isNull operator is selected. This should be done on DateField component
