Why my angular app is not loading my S3 Bucket?

i have angular app deployed to AWS S3 bucket that is not showing the S3 bucket files. environment file:

export const environment = {
    aws: {
        production: true,
        accessKeyId: process.env.accessKeyId,
        secretAccessKey: process.env.secretAccessKey,
        region: 'ap-south-1'
    }
}

and my service.ts has this code:

AWS.config.update({
        accessKeyId: process.env.accessKeyId,
        secretAccessKey: process.env.secretAccessKey,
        region: 'ap-south-1'
});

const bucket = new S3(AWS.config);

@Injectable({
  providedIn: 'root'
})

export class S3Service {

  bucketName: string = 'angular-upload-files-2023-2024';
  loader: EventEmitter<boolean> = new EventEmitter<boolean>();
  currentFolder: string = 'properties2023';

  constructor() {}

  getFolderContent(): Observable<any> {
    return new Observable((observer) => {
      this.loader.next(true);
      bucket.listObjectsV2({ Bucket: this.bucketName, Prefix: this.currentFolder, Delimiter: '/' }, (err: AWS.AWSError, data: S3.ListObjectsV2Output) => {
        this.loader.next(true);
        console.log(data)
        if (err) {
          observer.error(err);
        }
        else {
          let list: any[] = [];
          list = list.concat(data.CommonPrefixes?.map(m => { return { name: m.Prefix, contentType: 'folder' } }));
          list = list.concat(data.Contents?.filter(m => m.Key != this.currentFolder).map(m => { return { name: m.Key, contentType: 'file', modifiedTime: m.LastModified?.toDateString() } }));
          observer.next(list);
        }

      });
    })

  }
}

in bucket permissions I have public access and I have:

bucket policy:

{
    "Version": "2012-10-17",
    "Id": "Policy1637840001466",
    "Statement": [
        {
            "Sid": "Stmt1637839995898",
            "Effect": "Allow",
            "Principal": "*",
            "Action": "s3:*",
            "Resource": "arn:aws:s3:::angular-upload-files-2023-2024/*"
        }
    ]
}

and I have CORS:

[
    {
        "AllowedHeaders": [
            "*"
        ],
        "AllowedMethods": [
            "GET",
            "POST",
            "HEAD",
            "DELETE"
        ],
        "AllowedOrigins": [
            "*"
        ],
        "ExposeHeaders": [],
        "MaxAgeSeconds": 3000
    }
]
