Hi Felix,
This module is supported by the community, so it means that multiple developers contribute to it to maintain it. This module is not maintained by Mendix itself.
See here: Marketplace Content Support | Mendix Documentation
You can contribute to the connector, but using the Github link in the description.
Alternatively, you can see if there is one of the developers on the Mendix Community Slack channel
