Deploy Azure Bot as container on AKS instead of App Service

Question

Existing System: I have a bot developed using Bot Framework Composer and deployed on Azure App Service and Azure Bot Service.
Private Endpoint is enabled on Bot Service by following below article. https://techcommunity.microsoft.com/t5/iis-support-blog/private-endpoint-amp-direct-line-app-service-extension/ba-p/3736194. Bot works on private endpoint with above changes.

New Requirement: I have a requirement where in Azure App Service should be deprovisioned and Bot should be hosted on existing AKS node instead of App Service.

I have built docker image of Bot application and deployed on AKS. I am able to see "Your bot is ready" page. But when I go to https://hostname/.bot to check private endpoint, its empty and says page does not exist.

Question:
How do I setup private endpoint and Direct Line App Service Extension Configuration in docker based bot on AKS?
