NSI Outlet review for Sami B2B Wholesale Pricing

Janky app, doesn't work. We followed the instructions, added the app to the theme, and turned on the app toggle in theme settings, and we created a new volume pricing rule that covers all products. But when we click "Add a section" or "Add a block" in the product page theme editor, we can't find any new block or section that displays the volume pricing table we wanted to show. We tried to leave a message on their support site to get some support, that doesn't even work, the message wouldn't go through.
