Hello ,
Thank you for posting in the community your question and at this time there is not a Twinmotion 2023.1 for Revit, but it will be available as soon as the official release comes out. We are working on integrating Autodesk sign-in into Twinmotion but that is not planned for this upcoming release.
Once the Twinmotion 2023.1 for Revit release is available you will be able to get the new version from the Autodesk product page and click on the Twinmotion tile which will bring you to the download page.
Kind regards,
Vincent B.
