Deploy multiples schemes to different stores


I have a react-native application with several different schemes, in a whitelabel model, each scheme is a “different” application, changing only the assets.

We have around 20 different schemes, with different Signin configurations, I would like to know how I can implement the pipeline in an interesting way that can make this possible.

A workflow for each scheme? Put the necessary steps for each scheme in a single workflow? I did not find much support material on the subject, I would be very happy with guidance on this.
