Log to Dynatrace using Serilog and web.config .NET Framework API

Question

I have a .NET Framework web api and I would like to configure the web.config file so the Serilog logger to log into Dynatrace.

My web.config file is like

  <appSettings>
     <add key="serilog:minimum-level" value="Information" />
     <add key="serilog:using:Dynatrace" value="Serilog.Sinks.Dynatrace" />
     <add key="serilog:write-to:Dynatrace:accessToken" value="aaaaaaaaaaaaaaaaaaaa" />
     <add key="serilog:write-to:Dynatrace:ingestUrl" value="https://pppp.live.dynatrace.com/api/v2/logs/ingest" />

Which is the correct configuration?

My Dynatrace configuration works in appsettings.json files. The problem is only in web.config.
