      org.freedesktop.portal.Documents:
      @short_description: Document portal

      The document portal allows to make files from the outside world
      available to sandboxed applications in a controlled way.

      Exported files will be made accessible to the application via
      a fuse filesystem that gets mounted at /run/user/$UID/doc/. The
      filesystem gets mounted both outside and inside the sandbox, but
      the view inside the sandbox is restricted to just those files
      that the application is allowed to access.

      Individual files will appear at /run/user/$UID/doc/$DOC_ID/filename,
      where $DOC_ID is the ID of the file in the document store. It is
      returned by the org.freedesktop.portal.Documents.Add() and
      org.freedesktop.portal.Documents.AddNamed() calls.

      The permissions that the application has for a document store entry
      (see org.freedesktop.portal.Documents.GrantPermissions()) are reflected
      in the POSIX mode bits in the fuse filesystem.

        GetMountPoint:

        is mounted. This will typically be /run/user/$UID/doc/.

        @doc_ids: the IDs of the files in the document store
        @extra_info: Extra info returned

        Adds multiple files to the document store. The file is passed in the
        form of an open file descriptor to prove that the caller has
        access to the file.

        Additionally, if app_id is specified, it will be given the permissions
        listed in GrantPermission.

        The method also returns some extra info that can be used to avoid
        multiple roundtrips. For now it only contains as "mountpoint", the
        fuse mountpoint of the document portal.

        This method was added in version 2 of the org.freedesktop.portal.Documents interface.
