Where are correct instructions to cancel subscription?

Learning Sketchup was way over my head and I forgot to cancel the susbscription. Then on 12 April 2024, a Friday evening after business hours, I get an email with a renewal notice saying payment has been approved. I do not approve and this subscription needs to be canceled and refunded. Any Sketchup tech support can confirm I have not used Sketechup almost since it was purchased. I tried and could not follow the tutorials.

Instructions found on the Sketcup website do not work. When I tried to cancel the subscription, options to cancel are unavailable.
