Here's how to change permission to share files/folders that you upload (and generate a share link)

[DeJMan]

I noticed a lot of people asking about it. Since permissions isn't implemented as of the time of writing this post, this is my workaround.

    //this is a callback after the file/folder is created
    private void OnFolderCreated(File file)
    {
        StartCoroutine(ChangePermissionsCoroutine(file.Id));
        sharelink=file.WebViewLink;
    }

    // permission change
    IEnumerator ChangePermissionsCoroutine(string fileID)
    {
        // Endpoint to modify permissions for a file
        string endpoint = "https://www.googleapis.com/drive/v3/files/" + fileID + "/permissions";

        // JSON data with new permission settings (change as needed)
        string jsonData = "{\"role\": \"reader\", \"type\": \"anyone\"}";

        // Create a UnityWebRequest to send a POST request to update permissions
        UnityWebRequest request = new UnityWebRequest(endpoint, "POST");
        byte[] bodyRaw = System.Text.Encoding.UTF8.GetBytes(jsonData);
        request.uploadHandler = new UploadHandlerRaw(bodyRaw);
        request.downloadHandler = new DownloadHandlerBuffer();
        request.SetRequestHeader("Content-Type", "application/json");
        request.SetRequestHeader("Authorization", "Bearer " + AuthController.AccessToken);

        // Send the request
        yield return request.SendWebRequest();

        if (request.result == UnityWebRequest.Result.Success)
        {
            Debug.Log("Permissions changed successfully");
        }
        else
        {
            Debug.Log("Error changing permissions: " + request.error);
        }
    }
