Question: How can I use environment variables?

[josebruno2020]

What are you trying to accomplish? Please describe.
Helo, I'm building a carrier service, and I would like to know how to use environment variables in a NodeJs vtex-app.

What have you tried so far?
I tried to use dotenv, but with no success. I also tried to follow this tutorial, but also don't work.

Additional info
when I tried to do this:

    const token = process.env.TOKEN

    console.info(process.env)

    console.info(`TOKEN: ${token}`)

I received this message in my console:
