    before_workflow_action: function(frm) {
        var workflow_action = frm.selected_workflow_action;

        if (workflow_action === 'Reject') { 
            frappe.throw("hegvjh")
             
            let dialog = new frappe.ui.Dialog({
                title: __('Enter Rejection Reason'),
                fields: [
                    {
                        label: __('Rejection Reason'),
                        fieldname: 'rejection_reason',
                        fieldtype: 'Small Text',
                        reqd: 1
                    }
                ],
                primary_action_label: __('Submit'),
                primary_action(values) {
                    if (values.rejection_reason) {
                        frm.set_value('custom_reason_for_reject_', values.rejection_reason);
                        frm.save();
                        dialog.hide();
                    }
                }
            });
