How do you change the emulator shown in logcat in Android Studio

I am trying to make an app and I set up Android Studio to use Bluestacks as the emulator. This is no good because when I go to logcat all I see is endless processes and any error messages get lost. So I just want to use a normal AVD, like the Pixel 4. I can run the app on another AVD, but the new AVD is not shown in logcat. All I ever see is Emulator emulator 5554 in the dropdown list in logcat with No debuggable processes in red next to it and if bluestacks is not running then it says No connected devices. If I click on the dropdown list it is the only thing there. So how do I get logcat to connect to the AVD that I am running the app on?
