Hey @MichaelRensing ,
Welcome to the community! Feel free to Introduce yourself

To get a specific version (commit) or a different model (branch) in Power BI, you need to copy the URL of that version (commit) or model (branch) and paste it into the Power BI connector. This way, you can easily load that specific version into Power BI.
Similarly, if you want to receive a model (branch), you can use its URL. But keep in mind that you’ll get the latest version pushed to that model (branch).
