I am unable to figure out how to use the @sendgrid/inbound-mail-parser package to parse inbound emails. need some example code

Steps to Reproduce

Setup a parse route in sendgrid (linked here: https://www.dropbox.com/s/cb6lwrmon9qwjzq/Screenshot%202017-10-12%2016.03.49.png?dl=0 ) this is the contents of an example email to the route in ngrok: https://gist.github.com/machinshin/e38cf7d20ec6319edcfda63ff7aca594

I have connected the parseroute to my webhook like so:

router.post('/api/email/parseroute', (req, res, next) => {
// have also tried:
router.post('/api/email/parseroute', bodyParser.raw(), (req, res, next) => {

    console.log(`-------------`)
    console.log(req.body)
    console.log(`-------------`)
    console.log(req.rawBody)
    console.log(`-------------`)

}

---

{}

undefined

As you can see, req.body is empty, and req.rawBody is 'undefined' Thus, I am not clear on how to get access to the raw email data, nor what to do with that data afterwards and how to instantiate the inbound-mail-parser
