Hello Guys,
"OnRecordStart" refers to the moment when a recording starts, and in the context of data, it can refer to the beginning of a data collection or recording process. The presence of data generally refers to the fact that some data exists, without specifying the type or content of that data. For example, if a company says "we have data on customer preferences", that statement indicates that there is some information about customer preferences available, but it doesn't specify what that information is.
