Your executed documents

Your documents is the investor's own paperwork, filed automatically: the NDAs you have accepted, the agreement packs you have signed, each with its raise and status, and the share certificates you have been issued. Nothing needs uploading; signing and issue put them here. A company's own files, such as its information memorandum and financials, are not here: they are in that deal's dataroom, and the links at the top of the screen (and each raise name in the tables) open it.
