VirtualBox Mojave 10.13 WIFI issues

Hi guys
Great to join this community, i am soooo excited to start building an app.
However I seem to be doomed to be stucked at the Virtual Box installation already.
Thus, I am using Virtual Box 6.1. and Mojave 10.13 which works fine until you have to select the internet connection where I cant choose wifi but have to select ethernet which my computer doesnt have ( I only have WIFI).
Does anyone has an idea how to solve this ???

Best Regards
