I checked with Wise support and they told me that my account was with People's Trust (I dont know if all wise accounts are with this bank), however that's not one of the options when I try to link a bank account with western union, in which case Wise told me that I could not directly link my CA dollar account to western union
That being said, I ordered a Wise debit card to see if that works. Will let you know once i receive it if I am able to use it with western union.
If this doesn't work, check out Curve.app (referral link: https://www.curve.com/join#NMZKL59E). I've been paying all of my WU transfers with the curve card (it works like a debit frontend) and it has avoided me lots of money. I have used Bank of America, Chase, and another 2 French Bank cards and have never paid any sort of "cash advance fee" !!
