I can't find documentation for an endpoint listing user collaborations. The request below seems to work fine, with an exception of setting `fields` query parameter. The result doesn't include the `item` and other basic fields.
```
curl --request GET \
--url 'https://api.box.com/2.0/users/me/collaborations?fields=item&status=accepted' \
--header 'Authorization: Bearer ...' \
--header 'as-user: ...'
```
Could this be a bug?
