Open a new terminal

composer-rest-server

enter the admin card: admin@logistics-network

> ❕ Note: if you didn't note down it, open composer playground dashboard. The heading admin@something is the admin card name

enter "No" to everything except test explorer.

Now your composer-rest-server started. 🎉
