Cannot uninstall Hazel 5.2.1 demo

I'm running the demo of Hazel 5.2.1 on Ventura 13.x and cannot uninstall it.

If I drag it from apps folder to trash, it's icon stays in the menu bar.
If I reinstall it and open Hazel, It shows the Hazel window with a double red line saying two times 'Trial Mode ended.'
If I follow the instructions on https://www.noodlesoft.com/kb/how-to-uninstall-hazel/ I cannot find the uninstall button or it is missing.

Hope you can help me out here.

Did you reboot after throwing Hazel away?

I did not and after doing that this issue has been resolved. Thanks for your prompt response.
