Can't figure out is it possible to use multiple schemas in Hot Chocolate for ASP.NET Core

Question

I'm trying to start developing GraphQL API with Hot Chocolate library on ASP.NET Core but I can't figure out how to use different schemas for different endpoints. I know about schema stitching but it's not what I'm looking for. What I would like to implement, it is to be able to query different types from different endpoints, for example, I want to query user data from localhost:5000/graphapi and to query different admin data from localhost:5000/admin/graphapi Yes, it is possible to create to separate servers for this but I would like to have monolith API.

This is quite simple,

first setup your GraphQL configurations for your schemas:

public void ConfigureServices(IServiceCollection services)
{
    services
        .AddRouting()

    services
        .AddGraphQLServer()
        .AddQueryType<Query>()
        .AddMutationType<Mutation>();

    services
        .AddGraphQLServer("adminSchema")
        .AddQueryType<QueryAdmin>()
        .AddMutationType<MutationAdmin>();
}

Next we need to configure the mapping of the schemas to concrete routes:

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    app
        .UseRouting()
        .UseEndpoints(endpoints =>
        {
            endpoints.MapGraphQL();
            endpoints.MapGraphQL("/admin/graphql", schemaName: "adminSchema");
        });
}

done.
