Hi I added a singleton class

internal class HubClientsConnectedInfo
{
    private IHubCallerClients _clients;
    private IGroupManager _groups;

    public void Set(IHubCallerClients clients, IGroupManager groups)
    {
        _clients ??= clients;
        _groups ??= groups;
    }
    public IHubCallerClients Clients => _clients;
    public IGroupManager Groups => _groups;
}

then i register it in Program.cs

builder.Services.AddSingleton<HubClientsConnectedInfo>();

then i fill it on BaseHub.OnConnectedAsync
