@Andy Quang Anh Pham Welcome to Microsoft Q&A Forum, Thank you for posting your query here!
You can perform this scenario by using CopyBlobFromUrl (service doc) as you did in previous versions. In Python Track2 that is done with the BlobClient.start_copy_from_url()
method.
See our sample for this here. This sample even uses an external URL as the customer is looking to do.
