How to use self-provided Application Insights agent instead of the default one in App Services?

Question

I am trying to deploy Java application to the App Services via zip-deployment. I want to provide javaagent of version 3.0-PREVIEW (like in this guide: https://learn.microsoft.com/en-us/azure/azure-monitor/app/java-in-process-agent), but can't succeed. My deployment script looks like that:

az webapp delete \  
  -n ${APP_NAME} \  
  -g ${GROUP_NAME} \  
  --keep-empty-plan \  
  --keep-metrics  
az webapp create \  
  -n ${APP_NAME} \  
  -p ${APP_NAME}-sp \  
  -g ${GROUP_NAME} \  
  --runtime "JAVA|11-java11" \  
  || exit  
az webapp log config \  
  -n ${APP_NAME} \  
  -g ${GROUP_NAME} \  
  --docker-container-logging filesystem \  
  || exit  
az webapp config appsettings set \  
  -n ${APP_NAME} \  
  -g ${GROUP_NAME} \  
  --settings \  
    COSMOSDB_ENDPOINT=${COSMOSDB_ENDPOINT} \  
    COSMOSDB_KEY=${COSMOSDB_KEY} \  
    CLIENT_ID=${CLIENT_ID} \  
    CLIENT_SECRET=${CLIENT_SECRET} \  
    TENANT_ID=${TENANT_ID} \  
    APP_SP_ID=${APP_SP_ID} \  
    EVENT_HUB_CONNECTION_STRING=${EVENT_HUB_CONNECTION_STRING} \  
    EVENT_HUB_OFFSET_STORAGE_NAME=${EVENT_HUB_OFFSET_STORAGE_NAME} \  
    EVENT_HUB_OFFSET_STORAGE_KEY=${EVENT_HUB_OFFSET_STORAGE_KEY} \  
    APPINSIGHTS_INSTRUMENTATIONKEY=${APPINSIGHTS_INSTRUMENTATIONKEY} \  
    APPINSIGHTS_PROFILERFEATURE_VERSION=${APPINSIGHTS_PROFILERFEATURE_VERSION} \  
    APPINSIGHTS_SNAPSHOTFEATURE_VERSION=${APPINSIGHTS_SNAPSHOTFEATURE_VERSION} \  
    APPLICATIONINSIGHTS_CONNECTION_STRING=${APPLICATIONINSIGHTS_CONNECTION_STRING} \  
    ApplicationInsightsAgent_EXTENSION_VERSION=${ApplicationInsightsAgent_EXTENSION_VERSION} \  
    DiagnosticServices_EXTENSION_VERSION=${DiagnosticServices_EXTENSION_VERSION} \  
    InstrumentationEngine_EXTENSION_VERSION=${InstrumentationEngine_EXTENSION_VERSION} \  
    SnapshotDebugger_EXTENSION_VERSION=${SnapshotDebugger_EXTENSION_VERSION} \  
    JAVA_OPTS="${APP_SERVICE_JAVA_OPTS}" \  
  || exit  

Configurations for AppInsights look like this:

{  
  "XDT_MicrosoftApplicationInsights_PreemptSdk": "disabled",  
  "XDT_MicrosoftApplicationInsights_Mode": "recommended",  
  "XDT_MicrosoftApplicationInsights_BaseExtensions": "disabled",  
  "SnapshotDebugger_EXTENSION_VERSION": "disabled",  
  "InstrumentationEngine_EXTENSION_VERSION": "disabled",  
  "DiagnosticServices_EXTENSION_VERSION": "~3",  
  "APPINSIGHTS_PROFILERFEATURE_VERSION": "1.0.0",  
  "APPINSIGHTS_INSTRUMENTATIONKEY": "key",  
  "APPINSIGHTS_SNAPSHOTFEATURE_VERSION": "1.0.0",  
  "ApplicationInsightsAgent_EXTENSION_VERSION": "~2"  
}  

And APP_SERVICE_JAVA_OPTS equal to -Xms3072m -Xmx3072m -javaagent:/home/site/wwwroot/applicationinsights-agent.jar -Dserver.port=80 which refers to this jar: https://github.com/microsoft/ApplicationInsights-Java/releases/download/3.0.0-PREVIEW.5/applicationinsights-agent-3.0.0-PREVIEW.5.jar

However, looking at the container logs, I see the picture that hardcoded applicationinsgihts-agent-2.5.0.jar is getting picked up anyway and I can't do anything about it.

How do I configure my project to use new App Insights jar with ApplicationInsights.json config?
