[Session 3] Speaker schema not updated

[weirdyang]

 public class SpeakerType : ObjectType<Speaker>
    {
        protected override void Configure(IObjectTypeDescriptor<Speaker> descriptor)
        {
            descriptor
                .Field(t => t.SessionSpeakers)
                .ResolveWith<SpeakerResolvers>(t => t.GetSessionsAsync(default!, default!, default!, default))
                .UseDbContext<ApplicationDbContext>()
                .Name("sessions");
        }

        private class SpeakerResolvers
        {
            public async Task<IEnumerable<Session>> GetSessionsAsync(
                Speaker speaker,
                ApplicationDbContext dbContext,
                SessionByIdDataLoader sessionById,
                CancellationToken cancellationToken)
            {
                int[] sessionIds = await dbContext.Speakers
                    .Where(s => s.Id == speaker.Id)
                    .Include(s => s.SessionSpeakers)
                    .SelectMany(s => s.SessionSpeakers.Select(t => t.SessionId))
                    .ToArrayAsync();

                return await sessionById.LoadAsync(sessionIds, cancellationToken);
            }
        }
    }

            builder.Services
              .AddGraphQLServer()
              .RegisterDbContext<ApplicationDbContext>(DbContextKind.Pooled)
              .AddQueryType<Query>()
              .AddMutationType<SpeakerMutation>()
              .AddType<SpeakerType>()
              .AddDataLoader<SpeakerByIdDataLoader>()
              .AddDataLoader<SessionByIdDataLoader>();

I've updated the speaker model, added the speakerType, ran the migration and updated the database, however the schema in the browser still does not show the SessionSpeakers collection. Has there been any changes between the versions?

sorry realised it was renamed to sessions
