Ionic AppFlow builds in development instead of production mode - ionic-framework

Question

I'm using the Ionic AppFlow Live Update deployment feature without problems but the build is made using the development environment instead of production. I have a similar app using Live Update that builds correctly in production environment and I can't find any differences in the configuration of both apps.
I have two environment files:
environment.prod.ts
environment.ts
and the app is using the environment.ts configuration, which is for development.
I can install correctly the app in production mode in a device through USB using:
$ ionic cap copy --configuration=production
$ ionic cap open android
How can I force AppFlow to use the production environment for the build?

I realized that because I'm using the free AppFlow version there is no Environments option. So I changed the build script to:
"build": "ng build --configuration=production",
and it worked.
In the Basic Plan and above, you can create environments and environments variables, as described in the official documentation.
