[Jupyter] Request for Assistance with Docker Image Rebuild for My Profile

Dear Jupyter Team, I hope this message finds you well. I am writing to inquire about the process of rebuilding the Docker image associated with my profile on your platform. I have visited the site recommended (https://jupyter.rwth-aachen.de/service/profile/) and understand that I need to select my profile to trigger a new build of the Docker image used to spawn single-user containers. However, I currently not hold the manager role necessary to perform this action. Could you please advise on how I can obtain it? Your guidance on how to proceed with rebuilding the Docker image would be greatly appreciated. Thank you for your assistance. Best regards, Mehmet Özesenlik
