Install pods got a warning hermes-engine has added 1 script phase

Question

When I installed pods for the first time I got a warning in the terminal:

[!] [Codegen] warn: using experimental new codegen integration

[!] hermes-engine has added 1 script phase. Please inspect before executing a build. See `https://guides.cocoapods.org/syntax/podspec.html#script_phases` for more information.

But not get a warning hermes-engine has added 1 script phase when do pod install --repo-update. The app starts and runs on the simulator/device.

Can anyone explain what is it and should I fix it?

bundle exec pod install

I got the message a warning message:

[!] hermes-engine has added 1 script phase. Please inspect before executing a build. See `https://guides.cocoapods.org/syntax/podspec.html#script_phases` for more information.

The docummentation said to add

:hermes_enabled => true

in the file ios/Podfile

and also

hermesEnabled=true

in the file android/gradle.properties

So, after doing that I got this in my Podfile.lock:
