Yes, the dbdemos platform should work with the Databricks Community edition account. However, if you encountered an error while trying to use it, it's possible that there was some issue with the specific demo you were trying to install, or with your account configuration.

To troubleshoot the issue, you may want to try installing a different demo from the dbdemos platform and see if that works without any issues.
