HTTP API metrics not showing in CloudWatch automatic dashboard

I have created a simple HTTP API and tested it using cURL. When I go to CloudWatch, no metrics are displayed. My understanding is that AWS automatically collects default metrics on HTTP APIs. Wondering why they don’t show up?

I also have logging enabled on the API and the logging metrics (for that log group) show in the automatic dashboard. As do other services that I’m using (and have done nothing special to enable)–S3, etc.

Can someone please confirm that the HTTP API metrics should show in the automatic API Gateway dashboard, or provide some hint as to why I may not be seeing them.
