Incomplete docs for Elastic.Serilog.Sinks in combination with Serilog.Settings.Configuration

The documentation for the [Elastic.Serilog.Sinks](https://www.nuget.org/packages/Elastic.Serilog.Sinks) NuGet package mentions configuring the sink using [Serilog.Settings.Configuration](https://github.com/serilog/serilog-settings-configuration). It also provides an example `appsettings.json` with some of the settings that are available, but I've been unable to find what some of these settings mean. Most of them are pretty self-explanatory, but I haven't managed to find what the `Serilog.WriteTo.Args.includeActivity` setting does. Can anyone point me in the right direction? Thanks!
