Possible to connect debugger to observatory url?

Hey there,
My current app uses go-flutter and as such I have to start the application using ```hover run```, but once it starts up it provides me with an observatory listening url which I can then take and pop into DevTools and everything works just fine. I tried adding that url to the dart remote debugger, but that didn't work. I didn't expect it to, but was hopeful. Is there a way to manually connect the debugger to that url? (Ex. http://127.0.0.1:50300/yLwAgKUj2w0=/ ). I saw in the newest update to the plugin that Desktop and Web were back in, but unfortunately, they don't see when I run my application.

Thanks,
-MH

The issue names no files or tests; start by reproducing the setup with `hover run` and the displayed observatory URL, then inspect how the plugin discovers desktop and web applications. Done means the debugger can manually connect to that URL and attach successfully.
