how to access Github Actions workflow data via smart values?

I am able to see workflow results from Github Actions in Jira:
How do I access the info here via smart values? In particular, I am trying to access the build number. I have followed the directions for [finding the smart value for a field](https://support.atlassian.com/cloud-automation/docs/find-the-smart-value-for-a-field/) and can see the custom field that has only some of the info:
```
"customfield_10000": "{pullrequest={dataType=pullrequest, state=MERGED, stateCount=7}, build={count=2, dataType=build, failedBuildCount=1, successfulBuildCount=1, unknownBuildCount=0}, json={\"cachedValue\":{\"errors\":[],\"summary\":{\"pullrequest\":{\"overall\":{\"count\":7,\"lastUpdated\":\"2022-02-03T16:34:33.000-0800\",\"stateCount\":7,\"state\":\"MERGED\",\"dataType\":\"pullrequest\",\"open\":false},\"byInstanceType\":{\"GitHub\":{\"count\":7,\"name\":\"GitHub\"}}},\"build\":{\"overall\":{\"count\":2,\"lastUpdated\":null,\"failedBuildCount\":1,\"successfulBuildCount\":1,\"unknownBuildCount\":0,\"dataType\":\"build\"},\"byInstanceType\":{\"cloud-providers\":{\"count\":2,\"name\":\"Other providers\"}}}}},\"isStale\":true}}",
```
I also logged the values of `{{build.name}}`, `{{build.url}}`, `{{build.state}}` and `{{build.refs}}` in the audit log but I don't get anything helpful:
Any help would be appreciated. Thank you!

Start with the issue's linked Atlassian smart-value documentation and the logged customfield_10000 data, then verify how GitHub Actions build results are exposed. Done means providing a confirmed smart value or documenting that the build number is unavailable, with an example that can be checked in Jira's audit log.
