Fetch development field data from a JIRA issue

I am using the internal API to get the GitLab Development info from the development field but it only returns the summary of the information. This is the endpoint that I am currently using.

url = f"{jira_base_url}/rest/dev-status/latest/issue/summary?issueId={issue.id}&applicationType=GitLab&dataType=branch"

The response is something like this. I need to get the all the data related to development, including branch names etc.

The ID for issue XXX-00000 is 000000
