I use the following AppleScript (assigned to keystroke Cmd+Ctrl+5) to start screen recordings (adapted from [here][1]). If I create an Automator Quick Action and assign the keystroke to it, it takes 9s until the screen recording starts. If I call the script via `osascript ./screenrecord_starter.scpt` from the command line, it takes about 15s. Why does it take so long (and how can this be improved [either by how the script is called or by the script itself])?

    #!/usr/bin/osascript

    --  Setup screen recording (mimics 'Cmd-S-5')
    tell application "System Events" to keystroke "%" using {shift down, command down}

    --  Start the screen recording
    tell application "System Events" to tell process "Screen Shot"
	    repeat until exists its front window
		    delay 0.1
    	end repeat
	    if not (exists button "Record" of its front window) then
		    click checkbox "Record Entire Screen" of its front window
    	end if
	    click button "Record" of its front window
    end tell
