AWS WAFv2 Web ACL managed rule group statement scope-down statements

Terraform
1

I want to create an AWS WAFv2 web acl of Cloudfront scope. I am using AWS managed rules. For Some rules in the managed rule group I have a scop-down statement. The json that I get from AWS is as follows:

{
      "Name": "AWS-AWSManagedRulesAdminProtectionRuleSet",
      "Priority": 0,
      "Statement": {
        "ManagedRuleGroupStatement": {
          "VendorName": "AWS",
          "Name": "AWSManagedRulesAdminProtectionRuleSet",
          "ScopeDownStatement": {
            "ByteMatchStatement": {
              "SearchString": "abc",
              "FieldToMatch": {
                "UriPath": {}
              },
              "TextTransformations": [
                {
                  "Priority": 0,
                  "Type": "NONE"
                }
              ],
              "PositionalConstraint": "CONTAINS_WORD"
            }
          }
        }
      },
      "OverrideAction": {
        "Count": {}
      },
      "VisibilityConfig": {
        "SampledRequestsEnabled": true,
        "CloudWatchMetricsEnabled": true,
        "MetricName": "AWS-AWSManagedRulesAdminProtectionRuleSet"
      }
    }

The AWS documentation here says that scope-down statements are allowed in the Managed rule group statement. However when I read the Terraform docs here we don’t have any option for scope-down statements. When I try to create a rule like the following, it passes terraform validation, however when I apply it I get an AWS error that says that I have added two statements, where one is required. This is very confusing. Is there a way I can achieve this, if yes how? Any help will be highly appreciated.

rule                                {
        name                            = "AWS-AWSManagedRulesAdminProtectionRuleSet"
        priority                        = 0
        override_action                 {
            count                       {}
        }
        statement                       {
            managed_rule_group_statement {
                name                    = "AWSManagedRulesAdminProtectionRuleSet"
                vendor_name             = "AWS"
            }                      {
            byte_match_statement {
                field_to_match   { 
                    uri_path     {}
                }
                search_string    = "abc"
                text_transformation {
                    priority        = 0
                    type            = "NONE"
                }
                positional_constraint = "CONTAINS_WORD"
            }
        }
        visibility_config               {
            sampled_requests_enabled    = true
            metric_name                 = "AWS-AWSManagedRulesAdminProtectionRuleSet"
            cloudwatch_metrics_enabled  = true
        }
    }

thanks
