InvalidOperationException: Cannot consume scoped service 'Microsoft.AspNetCore.Identity.UserManager'

I tried using your library together with GraphQL.Server.Transports.AspNetCore.
When accessing the GrapQL endpoint, I get InvalidOperationException: Cannot consume scoped service 'Microsoft.AspNetCore.Identity.UserManager`1[CUSTOM_USER_CLASS]' from singleton 'GraphQL.Authorization.AspNetCore.IAuthorizationEvaluator'.

Startup.cs (ConfigureServices):

services.AddGraphQLAuth();
services.AddScoped<IDependencyResolver>(s => new FuncDependencyResolver(s.GetRequiredService));
services.AddScoped<AppSchema>();
services.AddGraphQL(o => { o.ExposeExceptions = false; })
    .AddGraphTypes(ServiceLifetime.Scoped)
    .AddUserContextBuilder(context => new GraphQLUserContext { User = context.User } );

services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);

Startup.cs (Configure):

app.UseGraphQL<AppSchema>();
app.UseGraphQLPlayground(options: new GraphQLPlaygroundOptions());

My policies are generated using an Excel sheet, so I don't think showing that code is necessary. The AuthorizationHandler i wrote for these policies is never triggered.

Creating a policy to use with Authorization

Hi, thanks for making this.

One thing left out of the documentation is how to create a policy.

           services.AddAuthorization(options =>
            {
                options.AddPolicy("AdminPolicy", policy =>
                    policy.RequireRole("Admin"));
            });

The above placed in Startup.cs ConfigureServices is an example of how to create one.
