How to remove HALion Symphonic Orchestra after trial expired

Hi,
I tried the trial for HALion Symphonic Orchestra.
I decided not to buy it.
Since the trial expired I have a window (attached) popping up every time I open my Cubase.

I’m on mac, Cubase 10, in my Steinberg Content Folder (Application Support/Steinberg/Content) is no Halion Subfolder.

Can somebody tell me how to get rid of it?

Thank you.
