Update Existing Cognito User Pool Group via CDK

Hi,

I have a Cognito User Pool with a user group. This simple configuration deploys fine the first time. Any subsequent attempts to run cdk deploy with or without changes errors out with group already exists in stack error. I'm using Java for my CDK

Here's the code I'm using to create the user poll + group

  public void generateStack() {
    // Create User Pool
    UserPool userPool = Builder.create(scope, "some-id")
        .accountRecovery(AccountRecovery.EMAIL_ONLY)
        .autoVerify(AutoVerifiedAttrs.builder()
            .email(true)
            .phone(false)
            .build())
        .email(UserPoolEmail.withCognito(REPLY_TO_EMAIL))
        .enableSmsRole(false)
        .mfa(Mfa.OFF)
        .passwordPolicy(PasswordPolicy.builder()
            .minLength(8)
            .requireDigits(true)
            .requireLowercase(true)
            .requireUppercase(true)
            .tempPasswordValidity(Duration.days(TEMP_PWD_VALIDITY_IN_DAYS))
            .build())
        .removalPolicy(RemovalPolicy.RETAIN)
        .selfSignUpEnabled(true)
        .signInAliases(SignInAliases.builder()
            .email(true)
            .phone(false)
            .preferredUsername(false)
            .username(false)
            .build())
        .signInCaseSensitive(false)
        .standardAttributes(StandardAttributes.builder()
            .email(StandardAttribute.builder()
                .mutable(false)
                .required(true)
                .build())
            .givenName(StandardAttribute.builder()
                .mutable(true)
                .required(true)
                .build())
            .familyName(StandardAttribute.builder()
                .mutable(true)
                .required(true)
                .build())
            .phoneNumber(StandardAttribute.builder()
                .mutable(true)
                .required(true)
                .build())
            .build())
        .userPoolName("some-pool-name")
        .build();
    Role adminRole = Role.Builder.create(scope, "role-id")
        .roleName("admin-role")
        .assumedBy(new AccountRootPrincipal())
        .description("This is a full access admin role for Ops Team")
        .maxSessionDuration(Duration.hours(12))
        .managedPolicies(List.of(ManagedPolicy.fromAwsManagedPolicyName("AdministratorAccess")))
        .build();
    // Add admin group
    new CfnUserPoolGroup(scope, "admin-users", CfnUserPoolGroupProps.builder()
        .description("Admin group for the  Ops team")
        .groupName("admin-ops")
        .precedence(0)
        .roleArn(adminRole.getRoleArn())
        .userPoolId(userPool.getUserPoolId())
        .build());
  }

Is there a way to stop CDK from trying to create a group if it already exists in the stack?

Thanks Kunal
