Hey @emrme. The config file in this repo is generated from the safe-deployments repo

Take a look to this doc page

A similar PR should be like this one

Once the safe-deployments package is released with your chain then we can update the SDK

Hey @yagopv, my PRs to safe-deployments repo are all merged already:

safe-global/safe-deployments#916
safe-global/safe-deployments#915
safe-global/safe-deployments#918
safe-global/safe-deployments#914

So now you are waiting for npm package release I guess?
