A way to download files with "New object" button

I want to add files to a collection but I cannot drag and drop into this collection, I cannot add it with "+".
And with "Formats" miniapp, I cannot do anything into Files which is very basic right now (I'm going to submit a few requests...). And I don't want to have them into a page!

I recommand to have several solutions but I would submit separate requests for each one.
Here, can you improve the “Add Object” button so that it more closely resembles the Anytype version, which has reached a good level of maturity?

This button should allow users to upload a file or a set of files to add them to a space.
