Do I have to use the Livestream?

No this is not necessary. You can make it easy for yourself, for example, by only working with the formation & line-up possibly with substitution assistance.

This can help a starting coach enormously.

You can also choose to record events (for example only goals) on the stream, but not to switch on the Livestream. So you’ll collect the data for the statistics, but don’t share anything.
