If it helps my AI says the following.... Note that I am the only user of this free account.  I have not done anything explicit with permissions.  I created the table I am trying to access and put data in it through the UI.  I can see when I look at the workspace in the gui the following...  Am I allowed to use database connect 18.0.0

he project is now reaching Databricks Connect correctly, but the current blocker is workspace permissions, not code or versioning.

Current state:

dependency aligned to Databricks Connect 18.0.0
cluster ID accepted
connection reaches Spark Connect endpoint
failure is now:
PERMISSION_DENIED: Cannot access Spark Connect
Meaning:

your token/user can authenticate
but this workspace/user is not allowed to use Spark Connect on that compute
What must be fixed in Databricks:

ensure the cluster supports Databricks Connect / Spark Connect
ensure your user has permission to attach/use that cluster
ensure Spark Connect is enabled/allowed for the workspace and compute policy
