Twinmotion 2021, has BIMotion been removed from the latest version

I have just been completing some of the great online learning for Twinmotion and noticed a section called BIMotion, however I do not see BIMotion my latest version of Twinmotion. I’m using a Mac and just wondering if this is something no longer in Twinmotion or if it is just in the Windows version of Twinmotion?

Thanks
