Is it possible to add a parameter to the Firebase default 'session_start' event?

Question

The title is the content. I want to add a parameter to the session_start event.

The document says that there is no parameter for the session_start event, but no information about the custom parameter.

Is it possible to add a parameter to the session_start event? Is it impossible to add a parameter to all the Firebase default event?

Answer 1

There's no way to add a custom parameter to the session_start event, or to any other automatically collected event, since parameters are added when you call logEvent and your app doesn't call logEvent for automatically collected events. Depending on the information you wanted to add to the session_start event, there may be other ways of gathering that information.
