Magic 2022x DataHub Plugin Development

It looks like the DataHub feature in Magic System of Systems Architect (MSOSA) is a plugin that has its own plugins for specific interfaces. Is that API documented anywhere so we could develop our own interface? We're currently connecting MSOSA to Jira and Jama in 2022x using a custom plugin, but it would be better if we could leverage the synchronization and data mapping features in DataHub.

Thanks!
