Steinberg Download Assistant - Downloaded Files - MacOS

I use Steinberg Download Assistant for all my Cubase, and other products. And I have installed everything successfully.
I am running out of space on my MacBook Pro (who isn’t???).
I am amazed to see Users/Myuser/Downloads/Steinberg/ is consuming about 68GB!

Can I delete all this, or do any Steinberg products refer to this folder when running, for example mediabay?
