(help) setting up with nightmare helper

Hi,

I used codecept with Puppeteer previously. Now that I want to set up a project using Nightmare helper, I cannot get it to run. Output of ‘npx codeceptjs run --steps’ is not showing any step i wrote.
Maybe I didn’t install all npm packages (so far I have codeceptjs, nightmare, nightmare-upload).

Also I’m still using the I syntax which should be accurate with the method I’m interested for my tests (triggerMouseEvents). I would very much appreciate some example which i found lack in the documentation on Nightmare helper (only one).
