Running dusk tests in parallel

Hello, I am running multiple Dusk Test at the same time, for increased automation. I call the dusk test in two different terminal widows with the artisan command:

php artisan dusk --filter testTrail

But what I noticed it that when I start a second test in an other terminal window, while the first test is still running, the first terminal window 'listens' the browser for the second test as well as the browser for the first test (see image below)

An error occurs when one of the tests finishes before the other. when one test is finished Both browsers close down, so I am unable to finish the second test.

Is there any way for me to run two tests (or more) at once?

Is there a way for me make sure the browser control is set to each terminal independently, not both running on the same terminal?

Thanks in advance.
