Running a Shortcut on Apple Watch

I’m new to automations and shortcuts, so bear with me.

I’ve created an automation that deploys when I arrive inside a geofence. The automation simply calls for a shortcut to run on my Apple Watch.

My issue is that the automation causes a notice to appear on my phone asking if it is ok to run the shortcut on my watch. I don’t want that to display, I just want the shortcut to start up a workout in the Fitness app.

How do I prevent that message from appearing on the phone?
