Expose localhost to Flywheel virtual server


I am running an NPM run server on http://localhost:4444 and need the Flywheel local virtual server to be able to connect with the localhost server (php cURL). Is there any way of exposing the localhost server to the virtualbox server?

I’ve tested and without using Local by Flywheel and running both the WordPress instance and the NPM run server on localhost I am able to connect cURL between them easily.
