I'm using the latest version of the library, which is 2.0.4. The question is, when I use the DetachAsync method, is it possible to use the same CDPSession instance again to attach to the page? The reason I'm asking this is because I'm trying to use the DetachAsync method in a loop, but when I do that, I get the following exception: "Protocol error (Target.detachFromTarget): Session is already detached.". If I'm not using the DetachAsync method, then I don't get this exception. I have also tried creating a new CDPSession instance, but I still get the same exception. I have also tried using the Dispose method of the CDPSession class, but I still get the same exception. I have also tried using the DetachAsync method of the PuppeteerSharp.CDPSession class in the following two scenarios, but I still get the same exception.
