Display only FileName and not Full Path in Angular Bucket Folder

In AWS S3 Bucket, I can see the folders but when I click on a folder, I can see the files but with full path.

example: current folder: myDocuments --- Files: myDocuments/file1.jpg --- myDocuments/file2.jpg and so on...

I want to show: ---- file1.jpg, ----- file2.jpg

here is the code:

service.ts:

getFolderContent(): Observable<any> {
    return new Observable((observer) => {
      this.loader.next(false);
      bucket.listObjectsV2({ Bucket: this.bucketName, Prefix: this.currentFolder, Delimiter: '/' }, (err: AWS.AWSError, data: S3.ListObjectsV2Output) => {
        this.loader.next(false);
        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);
        }

      });
   })
}

getUrl(key:string): Observable<any> {
    return new Observable((observer) => {
      this.loader.next(true);
      bucket.getSignedUrl('getObject',{ Bucket: this.bucketName, Key:key,Expires:60*5 }, (err: Error, url: string) => {
        this.loader.next(false);
        if (err) {
          observer.error(err);
        }
        else {
          observer.next(url);
        }

      });
   })
}

and in file-list.ts

ngOnInit(): void {
    this.openFolder(this.s3Service.currentFolder);
}

openFolder(folder: string) {
    this.s3Service.currentFolder = folder;
    this.s3Service.getFolderContent().subscribe(m => {
      this.contentList = m;
    })
}

Please try to help me and forward me to others links as I have read alot and found them useless.
