VLS Synchronization Frequency - what data is synced?

[DH1]

There is a setting called VLS Synchronization Frequency under Global Application Settings which controls the frequency of the VLS Synchronization. Not finding any documentation on exactly what the VLS Synchronization process does nor what data is being synced. Any insights into this process would be appreciated.

VLS Synchronization is a process that synchronizes data between the SAP Learning Solution system and the Virtual Learning Server (VLS). Data that is synchronized includes, but is not limited to, user information, course information, and learning asset information. The frequency of the synchronization is configurable and can be set to occur every hour, day, week, or month.

Is this in reference to the SuccessFactors Learning module? If yes then what user information is synced? Also what do quiz answers and course materials have to do with VLS (aka meetings in WebEx, Teams, Zoom, etc)?
