Add HTTP Client in .Net Maui

[softdevinc2]

I am attempting to utilize the Going.Plaid package inside a .Net Maui app (i.e. not a Blazor Hybrid). I copied the code from the Quick Start example below.

        // Add Going.Plaid services
        builder.Services.AddHttpClient();
        builder.Services.Configure<PlaidCredentials>(builder.Configuration.GetSection(PlaidOptions.SectionKey));
        builder.Services.Configure<PlaidOptions>(builder.Configuration.GetSection(PlaidOptions.SectionKey));
        builder.Services.AddSingleton<PlaidClient>();
        builder.Services.AddSingleton<ContextContainer>(new ContextContainer() { RunningOnServer = true });

I need to understand how I can access the HttpClient created in the first statement builder.Service.AddHttpClient(); In the Quick Start app an inject statement was utilized to make the HttpClient available in the c# code. How can I accomplish the same in a .Net Maui application?
