xcode - React Native: where to add post_install script in podfile?

Question

I've upgraded to XCode 12, and am following this article on how to resolve a simulator deployment target warning. It says to add the following post_install script to your podfile:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
    end
  end
end

but when I add it at the end of my podfile, I still get the same error: warning: The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 8.0, but the range of supported deployment target versions is 9.0 to 14.4.99. (in target 'RNBackgroundFetch' from project 'Pods'), and others like it.

What I Want To Know: Where exactly in the podfile should I add the post_install script? There's a code block in my podfile that starts with target '<project name>' do, and at the end of this block I already have this code:

post_install do |installer|
    flipper_post_install(installer)
end

Should I add the recommended code to this existing post_install script? Or should I add a separate post_install script at the end of the podfile? Or something else? I've tried both and I still get the same simulator deployment target errors.
