Error on create subscription for teams chat messages

[LuccaRebelloToledo]

I'm trying to create a subscription to receive notifications about user messages, but I'm receiving an ExtensionError. I'm basing myself on Team chats

I've tried to create a subscription with the sample code I've found on Microsoft but I received an error. My expectation is to create a subscription to capture all chat messages on Teams.

Permissions Granted:

My body:

{
    "changeType": "created",
    "notificationUrl": "https://teams.execute-api.us-east-1.amazonaws.com/dev/notification-listener",
    "lifecycleNotificationUrl": "https://teams.execute-api.us-east-1.amazonaws.com/dev/lifecycle-notification-listener",
    "resource": "/me/chats",
    "expirationDateTime": "2024-12-06T14:29:36.010Z",
    "clientState": "secretClientState",
}

The error I'm receiving:

Internal Server Error - 500 - 5157 ms

{
    "error": {
        "code": "ExtensionError",
        "message": "Operation: Create; Exception: [Specified method is not supported.]",
        "innerError": {

        }
    }
}

To make the subscription, your account must be a tenant other than 'Personal'.
