When try the screenshot key on mx keys mini in mac os monterey the screanshoot comes with .png [1] for the first monitor and for second with [2] and it can't be open unless you manually remove [1] or [2] of the file name so it can be examleOfName.png. I think there is mistake in the code that generates the name. The current state is : Screen Shot + {currentDate} + ' at ' + {currentTime} + '.png' + '[' + {theMonitorNumber} + '}'
But it should be Screen Shot + {currentDate} + ' at ' + {currentTime} +
'[' + {theMonitorNumber} + '}' + '.png'
