Self-signed SSL certificate for application development

How can I configure a self-signed SSL certificate for application development? When I run the application in Visual Studio, it works with HTTPS on the port defined in launchSettings.json. However, after navigating to /bin/Debug/net8.0 and running the .exe, the application doesn't work the same way. Unlike when running in vs, it runs on port 5000 and uses HTTP. (ASP.NET Core Web API)

dotnet dev-certs command - .NET CLI

The dotnet dev-certs command generates a self-signed certificate to enable HTTPS use in development.

How to correctly use the generated certificate? I've tried various solutions, and none of them have worked appsettings.json

    //"HttpsInlineCertAndKeyFile": {
    //  "Url": "https://localhost:8443",
    //  "Certificate": {
    //    "Path": "./localhost.pem",
    //    "KeyPath": "./localhost-key.pem"
    //  }
    //},
    //"HttpsDefaultCert": {
    //  "Url": "https://localhost:5004"

    "HttpsInlineCertFile": {
      "Url": "https://localhost:8443",
      "Certificate": {

        "Password": "password"
      }
    }
  }
}
