Accessing dotnetcore middleware AFTER a JWT Token is validated

Question

I am using JWT bearer authentication, configured as follows.

My problem is that the middleware is executing before the token is validated.

based on @leppie's comment, here is a solution that works.

public class ActiveUserFilter : IAsyncActionFilter
{
    public async Task OnActionExecutionAsync(
        ActionExecutingContext context,
        ActionExecutionDelegate next)
    {
        var userName = context.HttpContext.User.Identity.IsAuthenticated
        ? context.HttpContext.User.GetClaim("email")
        : "(unknown)";
        using (LogContext.PushProperty("ActiveUser", !string.IsNullOrWhiteSpace(userName) ? userName : "(unknown)"))
            await next();
    }
}

Inserted as follows...

services.AddMvc(
    _ =>
    {
        _.Filters.Add(
           new AuthorizeFilter(
               new AuthorizationPolicyBuilder(
                 JwtBearerDefaults.AuthenticationScheme,
                 IdentityConstants.ApplicationScheme)
               .RequireAuthenticatedUser()
                 .Build()));
        _.Filters.Add(new ActiveUserFilter());

        ...
