Authentication Settings for External Systems

Hi everyone,

I recently used the Authentication Settings for External Systems on my scratch org. That will be used in my application. I did this so that I can pull some objects data from my production org. The issue with this is that SFDX does not pull the metadata thats in the authentication settings. It simply ignores it which means I have to do it manually every time someone installs my app.

Does anyone know if I can do this using post install script? Or if there is a better approach?
