Launch FB Messenger from within Unity

Hi,

Is it possible to launch to the Facebook Messenger app from Unity?
Client wants an AR app to launch a Messenger chat bot they have created, just wondering if this is even a possibility?

So we don’t need to launch it inside the app, just to start the Messenger app and switch to it on the device.

Many thanks!
Andy.
