Retrieving Last Uploaded Chunk: It checks the last successfully uploaded chunk via the status URL to resume uploads without starting over.
Chunked Upload: The file is uploaded in customizable chunks (default is 10 MB), sequentially, to manage resources and facilitate easy resumption.
Monitoring Progress: Provides real-time updates on the upload progress, including the percentage completed and the estimated time remaining.
Completion: After all chunks are uploaded, a final operation reassembles the file. The server then returns relevant data, such as the file URL.
