how to configure a single-tenant Azure Bot with a single-tenant App Registration using Python Bot Framework SDK

I created a new single-tenant Azure AD app and a single-tenant bot because multi-tenant support is being removed/deprecated. But when I try to connect the bot using the Python Bot Framework SDK, I always get the same error:

“The application does not exist in your tenant.”

I tried adding auth_tenant_id in the Bot Adapter settings, but the SDK throws:

“undefined parameter: auth_tenant_id”

It seems like the Python Bot Framework SDK does not support this parameter.

Can you please help me understand how to correctly configure a single-tenant bot with a single-tenant app registration in Python so that authentication works?

# Get credentials from environment
APP_ID = os.environ.get("MicrosoftAppId")

# Configure adapter for multi-tenant authentication
settings = BotFrameworkAdapterSettings(
    app_id=APP_ID,
    app_password=APP_PASSWORD
)
adapter = BotFrameworkAdapter(settings)

# Create Flask app

        await turn_context.send_activity("👋 Bot connected successfully!")

    async def process():
        await adapter.process_activity(activity, auth_header, on_turn)

    # Run async function in event loop
    asyncio.run(process())

    return "Bot is running."
