How to use v3 generated client as a HTTP client library?

It seems unclear to me how to use the generated client code as a HTTP client library to goa service.
I figure there's a NewClient factory for creating clients generated for each goa service. Problem is there isn't any documentation/example on how to implement its doer, enc, dec params.

func NewClient(
	scheme string,
	host string,
	doer goahttp.Doer,
	enc func(*http.Request) goahttp.Encoder,
	dec func(*http.Response) goahttp.Decoder,
	restoreBody bool,
) *Client

The clue project includes a fully featured example comprised of three microservices: the front service which receives requests from the public internet via HTTP and the forecaster and locator services that serve gRPC requests coming from the front service (see diagram).

The front service implements two client packages, one for each service it makes requests to. For example the forecaster client package contains a Client struct which exposes a GetForecast method which makes a request to the downstream forecaster service.
