Telegrator.Hosting.Web gets and example of invalid JSON

{
  "TelegramBotClientOptions": {
    "Token": "YOUR_BOT_TOKEN"
  }

  "TelegratorWebOptions": {
    "WebhookUri" = "https://you-public-host.ru/bot",
    "DropPendingUpdates": true
  }
}

WebhookUri must use colon instead of equal
And another documentation problem in the filters:

public class DatabaseUserFilterAttribute : FilterAnnotation<Message>
{
    public override bool CanPass(FilterExecutionContext<Message> context)
    {
        // Cast to HostedTelegramBotInfo to access services
        if (context.BotInfo is not HostedTelegramBotInfo botInfo)
            return false;

        // Access DI container
        var dbContext = botInfo.Services.GetRequiredService<UsersDbContext>();
        var configuration = botInfo.Services.GetRequiredService<IConfiguration>();
        
        // Use services in filter logic
        var user = dbContext.Users.FirstOrDefault(u => u.TelegramId == context.Input.From?.Id);
        return user?.IsActive == true;
    }
}

This class is unsafe. DbContext is scoped, so if ValidateOnScope is true, exception will be thrown, or memory leak will be occured (if false). Please consider using IDbContextFactory or create scope.
