Deployment error in Azure Web App: StaticFile Handler 0x80070002 and missing configuration guide

**Hello team,**

I'm trying to deploy a bot using the `teams.ts` library to Azure Web App, but I get the following error when accessing the `/api/messages` endpoint:

```
Module: IIS Web Core
Notification: MapRequestHandler
Handler: StaticFile
Error Code: 0x80070002
Requested URL: https://bot8ca761:80/api/messages
Physical Path: C:\home\site\wwwroot\api\messages
Logon Method: Anonymous
Logon User: Anonymous
```

I've reviewed my configuration and the generated ARM/Bicep template, but I couldn't find any official guide on how to verify or adjust the Azure Web App configuration for bots built with `teams.ts`.

**Steps taken:**
- Using the `teams.ts` repo for my bot implementation
- Tried with:
- `teams.ts/tests/ai`
- `teams.ts/tests/botbuilde`
- Generated the Azure Bicep template with the Teams CLI ATK tool (version 2.0.0-preview.9)
- Deployed to Azure Web App
- Endpoint configured as `/api/messages`
- No static files at that path

**Expected result:**
- Official guide or recommended steps to verify/configure Azure Web App for bots built with `teams.ts`
- Suggestions to resolve error 0x80070002

**Additional notes:**
- I couldn't find documentation for this scenario in the official docs.
- Is there any example of a successful Azure Web App configuration for bots with `teams.ts`?

Thank you for your support.
