I'm setting up the environment on Cloud9 IDE, and getting the following error: ImportError: libGL.so.1: cannot open shared object file: No such file or directory

Full trace:

python3 $GETTING_STARTED_DIR/src/modules/grafana/create_grafana_dashboard_role.py --workspace-id $WORKSPACE_ID --region $AWS_DEFAULT_REGION

Hi Doron, thanks for raising this!

We actually have this as a step in our setup for Cloud9: https://github.com/aws-samples/aws-iot-twinmaker-samples/blob/main/CLOUD9_SETUP.md?plain=1#L115-L123

But it seems easy for users to miss it accidentally. Wondering if you had any suggestions on ways we can simplify the setup or make it more visible

Yep, seems I've missed the reference to this document. Since it is there, maybe the only thing I can suggest, is lowering the Cloud9 note to the Prerequisits section of the main README file.

FYI: updated the README with your suggestion in https://github.com/aws-samples/aws-iot-twinmaker-samples/pull/33 Thanks!
