Good day! I'm planning to add wholesale for customer that has VIP acct, first they need to  log in first to access the wholesale page, I already tried this one https://www.envision.io/blogs/ecommerce-pulse/80312001-how-to-add-a-wholesale-area-to-your-shopify-s.... but it didn't work, Hoping for some expert out there to help me on this, Thank you so much!
