description of each role, please refer to our support documentation.Nested objects
When creating a collaboration there are two nested objects within the request body:accessible_by and item.
The accessible_by object specifies who the item should be shared with and
includes a group id and the type. The type field should always be set to
group.
The item object specifies what is being shared. It includes a type field
which should be set as file or folder, and an id for that file or folder.
