List the users who have read or write access to a data release.

Returns the current membership of the release's Globus permission groups as a list of permission assignments, each pairing a Globus username with the read or write permission that user holds:

• read → members of the release's read-only (R) group, who may view the release and its files.
• write → members of the release's read-write (RW) group, who may view and modify the release and its files.

The response is a flat list; a user who belongs to both groups appears once per permission level.

.. code-block::

[
    {"globus_username": "user1@example.org", "permission": "read"},
    {"globus_username": "user2@example.org", "permission": "write"}
]

The caller must have an existing role on the release; otherwise a 403 Forbidden is returned.

Note: permissions are read from the release's Globus groups directly. Publishing a release removes these groups, so this endpoint is intended for releases that have not yet been published.

:param id: The ID of the data release whose permissions to list. :param token: A valid bearer token for the user making the request. :raises ForbiddenException: If the caller has no role on the release. :raises NotFoundException: If no data release exists for the given ID. :return: The active read and write members of the release.
