elm-playground | Playground attempts to add a layer of abstraction | Functional Programming library

I want to make http requests from my elm program. I use the openapi-generator https://eriktim.github.io/openapi-elm for the http requests: https://github.com/eriktim/openapi-elm, The only example I could find is this:
https://github.com/eriktim/openapi-elm/tree/master/example
There, a request has e.g. type Api.Request Api.Data.PlanetList and is converted with the send function: (Result Http.Error a -> msg) -> Request a -> Cmd msg.
The send function takes a function to convert the Request result to msg but but returns it wrapped in Cmd. The update function has type update : Msg -> Model -> ( Model, Cmd Msg ) So as long as the request is made in the update function and the result is put in the return value the framework will get msg out of Cmd.

Now I want to make requests in my program, but I'm using playground game as my main function (example) where the update function is update : Computer -> Model -> Model so the "trick" from the example project is not applicable. How can I still get the values from my request call then?
