I've implemented override build and run scripts in apphosting.yaml following this documentation https://firebase.google.com/docs/app-hosting/configure#override-scripts but it doesn't work. I discovered the we can override the run script by add runCommand in runConfig (https://github.com/FirebaseExtended/firebase-framework-tools?tab=readme-ov-file#runconfig) and this works. But to override build command i can't find the right documentation
