Empty credentials for registration only apps

[lambda-science]

Hello, thank you very much for this fantastic package. It helps a lot put streamlit apps into "semi-production".
I want to ask, is it possible do to an initial empty config.yaml like:

cookie:
  expiry_days: 1
  key: some_signature_key
  name: streamlit-pythia-auth
preauthorized:
  emails: 
    - [email protected]
    - [email protected]
    - [email protected]

So a yaml that doesn't contain initial credentials key but only preauthorized email so that we can push it to our private repo without pushing initial "admin account" hash ?
Basically I want to push my auth yaml file to my repo for deploymenent with a restricted list of user that will use it, but I don't want to put an initial account inside it.
