I want to know how to invoke functions defined in `packages/functions` in my NextJS application inside `packages/web`. Example:

```auto
new Function(stack, 'my-function', {
    handler: 'packages/functions/index.handler',
});

```

```auto
lambda.invoke({
    FunctionName: 'my-function',
    InvocationType: 'Event',
    ...
});

```

For now, I do not want to use SQS, Events or API. The AWS Lamba offers a feature that is possible to invoke a function asynchronously just passing `InvocationType: 'Event'`.

How can I do that in SST framework?
