     - Create a secret for the CICD agent, using the page shown in Figure S6.  At the time you create this, you will need to safely store the client secret and client id, as prompted by the web page.  These will be used below.

 Now, is is convenient to use environment variables for context.  Note that for our example, there is only one aws account apropos, however this is not always the case for an active professional, so while `DATABRICKS_AWS_ACCOUNT_ID` is the same as `AWS_ACCOUNT_ID` here, it need not always be the case.

I have noted that due to some reponse caching it takes a while to disappear from select queries (much longer than disappearance from the web page), and you may want to bounce the `stackql` session to hurry things along.  This is not happening on the `stackql` side, but session bouncing forces a token refresh which can help cache busting.
