Where is SpectraLayers hiding?

I’m using Cubase 11 pro. I don’t appear to have the 'SpectraLayers ’ version 1 on there. I understand it should come with Cubase 11 Pro. I haven’t got the option in audio tab for ‘extensions’. I’ve looked at my Steinburg Download Assistant and under SpectraLayers it only has the Pro 6 and 7 versions (which you have to purchase). Any idea ??? Thx

I think it’s in the Cubase 11 download break down in Download Assistant

AHH. found it, many thanks
