Connecting to Dataverse api in C#

I am trying to learn the dataverse API using C#. I am following the code in this github: https://github.com/microsoft/PowerApps-Samples/blob/master/dataverse/orgsvc/C%23-NETCore/GetStarted/ConsoleApp%20(public)/Program.cs

I changed the login information and the appID to my app registration's client id and added a redirect URL of http://localhost.

The app registration does have API permissions to Dynamics CRM.

However, I still get an error

Original exception: AADSTS7000218: The request body must contain the following parameter: 'client_assertion' or 'client_secret'

This is my connection string:

static string connectionString = $@"
AuthType = OAuth;
Url = {url};
UserName = {userName};
Password = {password};
AppId = {appId};
RedirectUri = http://localhost;
LoginPrompt=Auto;
RequireNewInstance = True";

I cannot figure out what the issue is. Any help would be greatly appreciated.

Create a new secret for your application registration in Active Directory/Entra and include it in the connection string as the 'client_secret' parameter. With this, you will not need your username and password in the connection string.

Do not modify the value of setting AppId.

In the connection string it should be set like this: AppId=51f81489-12ee-4a9e-aaae-a2591f45987d;
