How does one create a TranslationServiceClient using a json as authentication?

Question

Hello and thanks for reading my question.

I'm working on transitioning some code from Google.Cloud.Translation.V2 to Google.Cloud.Translate.V3 because we need to make use of the api advanced features. We are using a TranslationClient to get us the translations (from the V2 library) but we need to instead use the TranslationServiceClient (from the V3 library.) I'm having trouble instantiating a TranslationServiceClient with our credentials. The way to do it in V2 is straightforward:

TranslationClient.Create(GoogleCredential.FromJson("{\"the credentials\"}"));

From reading the documentation it is clear to me that to create a TranslationServiceClient without the default settings you need to use a TranslationServiceClientBuilder and give that the credentials. I couldn't find any examples, all of the code snippets use TranslationServiceClient.Create() which doesn't allow for any arguments.

Since the goal is to create a TranslationServiceClient using a json as authentication, one way to do this is as follows:

TranslationServiceClient client = new TranslationServiceClientBuilder {
                        JsonCredentials = "{\"the credentials\"}"
                    }.Build()
