Understanding the process of retrieving a data value from HTML in an AngularJS directive

I'm a beginner with Angular and I'm trying to pass some data to my angular directive from the template.

<div class="col-md-6" approver-picker="partner.approverPlan.data" data-pickerType="PLAN"></div>

I have this in multiple places in my angular template and I need to know which picker is being clicked in my Angular code.

I am considering reading the value of data-pickerType in my directive. (I can do this in jQuery but not sure how in Angular)

This is what my directive code looks like:

Partner.Editor.App.directive('approverPicker', [
'$compile', function ($compile) {
    return {
        scope: {
            "approvers": "=approverPicker"
        },
        templateUrl: '/template/assets/directive/ApproverPicker.html',
        restrict: 'EA',
        link: function ($scope, element) {
              ...........
        }
    };
  }
]);

Any suggestions on how to read the data-pickerType value in the directive or perhaps a better approach to achieve this?

To retrieve the data attributes in an Angular directive, you can utilize the `attrs` variable within the link function.

Partner.Editor.App.directive('approverPicker', [
  '$compile', function ($compile) {
      return {
        scope: {
          "approvers": "=approverPicker"
        },
        templateUrl: '/template/assets/directive/ApproverPicker.html',
        restrict: 'EA',
        link: function ($scope, element, attrs) { //passing attrs variable to the function
          
            //accessing the data values
            console.log(attrs.pickertype);

            //you can access any html attribute value for the element
            console.log(attrs.class);

        }
      };
   }
]);
