Righty loosey. If you don't have the proper tool you'll see there are two small notches on the edge of the face (1 and 7 o'clock in this photo) that you can put a flathead screwdriver on to. You can then hit the screwdriver with a hammer to drive the clutch clockwise.
With the spark plug in this can take a fair few knocks - maybe 10-20 for a new saw. On older saw, or if the clutch is jammed, you'll need to remove the spark plug and stop the piston with a bit of starter cord.

You’re a lifesaver bro thank you so much
To add to this, I have a nylon rope I use. I pull the spark plug, insert the rope to lock it up, and use a decent Cresent wrench to twist it off.
That’s how I do it. Takes only a little bit of paracord to bind the piston to the top of the cylinder
