Inspect Browser Timeline in k6 Browser Test not displaying any traces

I am currently running a k6 browser test via the command: k6 cloud run --local-execution scriptName.js

However, I am not seeing any data under the Browser Timeline section of the dashboard as documented here:

In place of actual data, the panel reads: “No traces found for this test run and/or scenario.”

I am unclear what the requirements are in order to get this information to display. Are there any pre-requisites needed, either from a grafana cloud or Otel setup standpoint, before I would expect to see trace data here? My script is performing basic page.goto and click actions, and I can see the other metrics expected such as browser vitals (FCP, LCP, FID, CLS, etc).

UPDATE
I tried running this with: k6 cloud run scriptName.js (no local execution), and the data is available in the browser timeline panel. So it appears to be an issue with running locally and streaming to the cloud. I am not clear if this is expected behavior or not.
