According to your description, I followed this avocado-console-client sample to test it on my side. I could make it work as expected, you could refer to the steps below:

1.Update Microsoft.IdentityModel.Clients.ActiveDirectory to the latest stable version (3.13.8) via NuGet

2.Modify the function authCtx.AcquireToken to authCtx.AcquireTokenAsync as follows:

var authResult = await authCtx.AcquireTokenAsync(avocadoResourceUri, thisConsoleAppClientId, thisConsoleAppUri, new PlatformParameters(PromptBehavior.Auto));

3.Register your native app and modify thisConsoleAppClientId and thisConsoleAppUri

Sign in to the Azure Portal, click "Azure Active Directory" > "App registrations", click Add buttion to add your native app as follows:

For thisConsoleAppClientId(your client app Id), you could find it on Azure Portal:

For thisConsoleAppUri (the return url of your app):

Note: In order to access Avocado API, you need to assign your app with the delegated permission to Avocado. You could follow the steps below:

Select you AD app on Azure, In the Settings blade click "Required permissions" to add a permission and choose "Have full access to the service" option.

Note: You could input Avocado [wsfed enabled] to select the Avocado API.

Upon the configurations, you could test it. Here is my code snippet:

Program.cs

class Program
{
    static void Main(string[] args)
    {
        AvocadoDemo();
        Console.WriteLine("press any key to exit...");
        Console.ReadKey();
    }

    static async Task AvocadoDemo()
    {
        string thisConsoleAppClientId = "c588cf8d-8651-4b37-8d10-49237cf92f8e";
        Uri thisConsoleAppUri = new Uri("http://bruceConsoleForAvocado");
        string avocadoResourceUri = "https://microsoft.onmicrosoft.com/Avocado";
        // Get the access token for Avocado. This will pop up the login dialog and consent page for the first time.
        // Then the token will be cached in the FileCache, and AcquireToken will renew the token automatically in the subsequent run.
        AuthenticationContext authCtx = new AuthenticationContext("https://login.windows.net/microsoft.onmicrosoft.com", new FileCache());
        var authResult = await authCtx.AcquireTokenAsync(avocadoResourceUri, thisConsoleAppClientId, thisConsoleAppUri, new PlatformParameters(PromptBehavior.Auto));

        if (!string.IsNullOrEmpty(authResult.AccessToken))
            Console.WriteLine("accessToken: " + authResult.AccessToken);

        // call Avocado API
        var baseAddress = new Uri("https://avocado");
        var cookieContainer = new CookieContainer();

        // POSTing a new execution will invoke a redirect, so for example purposes we are disabling it here.
        using (var handler = new HttpClientHandler() { CookieContainer = cookieContainer, AllowAutoRedirect = false })
        using (var client = new HttpClient(handler) { BaseAddress = baseAddress })
        {
            // Need to set this cookie for avocado api to work.
            cookieContainer.Add(baseAddress, new Cookie("deep_link", "-1"));

            // add your access token in the header
            client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", authResult.AccessToken);

            // Here's a GET example
            var avoResultGet = client.GetAsync("/schedules/7215.json").Result;
            var strGet = avoResultGet.Content.ReadAsStringAsync().Result;
            Console.WriteLine("Avocado API returns: " + strGet);
        }
    }
}

Result

Since you have been authenticated, you could refer to API Documentation to invoke the specific APIs as you wish.
