This explains the functional steps within the sequence. For all the other XML details please refer to Formats and syntax

Essentially it is just calling Timelines.ImportMarkersFromString() with the correct arguments (see Timelines.ImportMarkersFromString for other solutions):

1. Handles.GetTitanIdFromHandle(“timelineHandleUN=1”) is used to get the TitanId from a specific usernumber as the function needs the titanId and not a handle
2. “<Version />” is the absolute minimum string as importMappingVersion
