Is it possible to allow file uploading for gif, xls, ppt, pptx, doc, docx

Hello sendbird developers!
I received the request to learn ability for allowing additional file types to upload:
‘.jpg’, ‘.jpeg’, ‘.png’, ‘.gif’ ‘.xlsx’, ‘.xls’, ‘.doc’, ‘.docx’, ‘.ppt’, ‘.pptx’, ‘.pdf’
I guess some of them are already allowed, but not all.
So the question is is it possible to allow uploading of all mentioned filetype extensions? Maybe in new version we will have this option?
