ElixirConf 2023 - German Velasco - Using DDD concepts to create better Phoenix Contexts

In the video he discusses this at 26:48. He wraps the 3 bounded contexts together in a specific “use case” function at the app layer. He passes an event data structure through these contexts, an event has the minimum amount of information necessary to avoid coupling the contexts together.

Much of the discussion here seems to be about the problem of composing contexts? So what do we think about the approach given in the video?
