How to import node module passing subClass argument in ES6?

Question

In JS I require in the node module gm (which I want to use with imageMagick rather than the default graphicsMagick) while passing an argument like this:

 var gm = require('gm').subClass({ imageMagick: true });

How can I do that in ES6?

import gm from "gm";
gm.subClass({ imageMagick: true });

doesn't work, because gm defaults to GraphicsMagick which isn't installed.

Answer from @Felix Kling works:

import gm from "gm";
const im = gm.subClass({ imageMagick: true });

...using im from here on!
