Wavelab 12 efx slot that will load Sonobus

Hi, i’m trying to use Sonobus with Wavelab but keep getting an error message that Sonobus won’t work there as a plug-in in montage. It was suggested that Sonobus needs to be in a master output efx slot. Sonobus transmits the audio stream over the network on UDP . I use it in other daws on my network. It won’t load at all in WL Montage. The error is ~ Sonobus will not work in this type of location ~ Hoping for some assistance.
Thank-you
