I've taken your stack one step further, with a completely dockerised solution that uses Firebase as an authentication solution (authentication is missing from the current low-code example). It can be run locally or on a cloud provider that runs containers (e.g. GCP Compute Create-With-Container). See here: https://github.com/dvasdekis/react-admin-hasura-firebase/
Thanks to gavinray also for the help with this!
