NaturalONE Jira integration?

The video https://youtu.be/s5vXcs1FuKc shows nicely how the NaturalONE/Eclipse task management interacts with Jira through Mylyn. But has anyone managed to get that integration working recently? Atlassian has stopped the development of their Mylyn Jira plugin years ago and Mylyn itself also does not deliver a Jira connector anymore. The only Mylyn connector working with the Eclipse version of the current Software AG Designer build seems to be the Trac connector.
