My js-ipfs node is running on the browser, I want to download the files stored on ipfs, what should I do?

I use ipfs.get (file CID) and get the data of BufferList. How can I restore this data to the original file and download it to the local? I tried to download it with Blob, but it can only restore string documents, but not other types. I need someone to help me, thank you

I need help very much and look forward to your reply!
