How to start my personal Zoom room using Siri on macOS?
Solution: Use a script saved an application
Siri on macOS doesn’t support third-party integration yet, but it can launch applications—thus, we can save an AppleScript as an application and have Siri activate it.
Steps

Open Script Editor.

Create a new document and type in the following:
tell application &quot;zoom.us&quot; to activate

tell application &quot;System Events&quot;
    tell process &quot;zoom.us&quot;

        set StartMeeting to menu item &quot;Start Meeting&quot; of menu &quot;zoom.us&quot; of menu bar 0

        repeat while not enabled of StartMeeting
            delay 0.25
        end repeat

        click StartMeeting

    end tell
end tell

The repeat while not enabled section makes the AppleScript wait until Zoom has finished launching before trying to open your Zoom room. Otherwise, it won’t work.

Save it, and in the save dialog, call the script “My Room Zoom”, save it to the /Applications folder, and set the file format to “Application”


Done!


Now you can say “Hey Siri, open my Zoom Room” and Siri will interpret your command as “launch the application called ‘My Room Room.’”
This application will launch Zoom if it isn’t already running and then start a meeting with your default settings.
Note that the first time you launch the application, it will ask for some permissions on Catalina, and you’ll have to go into System Preferences &gt; Security and Privacy &gt; Privacy &gt; Accessibility and tick the box for “My Zoom Room.”
Bonus: Create a global keyboard shortcut

Open Automator

Create a new document of type “Quick Action” (formerly called Services)

Drag in a “Run AppleScript” action and type in:
on run
    tell application &quot;My Zoom Room&quot; to activate
end run


Adjust the Quick Action image and colour if you want, and save it as “Open my Zoom Room.”
It should look something like this:


Now open up System Preferences &gt; Keyboard &gt; Shortcuts. Go to “Services” and scroll until you see “Open my Zoom room.” Click to set a shortcut. I use Cmd-Ctrl-Opt-Z.


Done!
You can now press Cmd-Ctrl-Opt-Z anytime anywhere to launch your personal Zoom room, regardless of whether Zoom was already running or not.
