Axe fx 2xl wah- mc8 Omni port

I’m looking for step by step directions on how to use the mc8 Omni port to set up a wah from the axe fx 2xl.
Thru a midi cable. I have wah working with an expression pedal connected directly into the axe fx, however I’d prefer less lengthy cable and really use more of the flexibility of the mc8. Any help would be appreciated. I’ve seen all the you tube videos However I feel like I’m missing something.
Thank you,

anyone have any info on this? thank you

its the axe fx 3 sorry
