I'm trying to make calls to some of our internal apis from the an umbraco site but I am having trouble with the authentication. The apis have been secured with azure ad and the umbraco site has been given a client id and some roles which will allow it to call the app.

When I try to implement the following code in the program file:

        builder.Services
            .AddMicrosoftIdentityWebAppAuthentication(builder.Config, "ApiSettings:AzureAD")
            .EnableTokenAcquisitionToCallDownstreamApi()
            .AddInMemoryTokenCaches();

The site throws an error:

TypeLoadException: Could not load type 'Microsoft.Identity.Web.MicrosoftIdentityOptions' from assembly 'Microsoft.Identity.Web, Version=3.2.0.0, Culture=neutral, PublicKeyToken=0a613f4dd989e8ae'.

Unknown location

ReflectionTypeLoadException: Could not load all types from "Umbraco.Cloud.Identity.Cms, Version=13.0.1.0, Culture=neutral, PublicKeyToken=null" due to LoaderExceptions, skipping: . System.TypeLoadException on Microsoft.Identity.Web.MicrosoftIdentityOptions: Could not load type 'Microsoft.Identity.Web.MicrosoftIdentityOptions' from assembly 'Microsoft.Identity.Web, Version=3.2.0.0, Culture=neutral, PublicKeyToken=0a613f4dd989e8ae'.

Does anyone know how to implement this so I can generate a token when making my http client request?
