Troubleshooting Dust Agents Connection Issues with Google Drive

Hi all, don't know if this channel is working on weekend, but trying just in case ! I managed to build and use a few Dust agents based on my google drive resources. But then I wanted to change the structure of my google drive folders (to ad a new root folder). I wanted to give access to those new root folder and "changed permission" for that. But since then it looks like I lost connection with google drive (see picture). Any insight ? Many thanks !
