IdnetityServer - get user info in API protected by JWT

Question

I'm using IdentityServer4 and im trying to figure out how to get current userId (guid) in protected API.. Upfront is BFF which proxy all requests to API. When I look in http context there is no user info available.. and User.isAuthenticated is always false.

What soud i make to get some user data in that API? Minimal current user UserId to query database..

.AddAuthentication("token")  
 .AddJwtBearer("token", options =>
        {
            options.Authority = "https://localhost:6666";
            options.MapInboundClaims = false;

            options.TokenValidationParameters = new TokenValidationParameters()
            {
                ValidateAudience = true,
                ValidTypes = new[] { "at+jwt" },
                
                NameClaimType = "name",
                RoleClaimType = "role"
            };
        });

The _contextAccessor.HttpContext.User.Identity.IsAuthenticated is always false
