Problem to add a member on file or folder share.

Hello,
I can't add a member to a file or folder when I give write permission (editor). (No problem with the viewer read right).

Here is the body of my query:

{
        "file": "id:Q2EU1CT92JwAAABBAABGcg",
        "members": [
            {
                ".tag": "email",
                "email": "xxxxxxx@gmail.com"
            }
        ],
        "quiet": false,
        "access_level": "editor"
    }

The answer is :

{
        "error_summary": "access_error\/no_permission\/",
        "error": {
            ".tag": "access_error",
            "access_error": {
                ".tag": "no_permission"
            }
        },
        "user_message": {
            "locale": "en",
            "text": "You don’t have permission to perform this action."
        }
    }

Here are my permissions:

What permission is missing?

Thanks.
