I need help on how to setup our X32 to route channels 1-25 to the usb output and use OBS to stream online

Hi all.

I'm really new to this and I have been watching several Youtube video tutorials to be able to capture the audio from the X32 and livestream using OBS.
So far all the videos I'm seeing don't explain how to get the audio from all the channels, all the video are only showing how to setup channels 1-8 which make sense. We use channels 1-25 and would like to have all these channels on our livestream. Can someone assist me me guidance on how I need to set this up? This video is helpful but per my understanding is only capturing whatever is connected to channels 1-8 on the console.

Thank you
