logStreams does not support aggregation

Issue: -
- I'm trying to add a log stream chart to my custom dashboard that filters logs based on a condition, like | where ([lambda.name] =~ "my-lambda-function-name"). I also want to include a list of all Lambda function names alongside the chart, so I can click on any of them to view the logs for a specific function.
- When I used this APL query:
```
['my-dataset-name']
| where ['lambda.region'] == "us-east-1"
| summarize by ['lambda.name']
```
- I got an error (as shown in the screenshot).

I'm wondering if Axiom allows grouping or aggregating log streams, and if not, is there a workaround for this?

i have raised this issue over [axiomhq/docs](https://github.com/axiomhq/docs/issues/90) as well

Review the APL query and the linked axiomhq/docs#90 issue first. Done means establishing whether logStreams supports grouping or aggregation and documenting an available workaround or the required behavior; no source file or test is identified in this report.
