Visual Learner! Adding Sezzle to my WooCommerce shop

I have been trying to add/activate Sezzle for almost 3 weeks now.

I am a visual type of person and NOT a coder. I have even tried to PAY people to put Sezzle in my shop. Everyone keeps telling me to follow the step-by-step instructions (even on the phone!). If I could do that I wouldn’t be here! Sorry, just super frustrated. I have seen videos that help with Shopify stores but NOTHING for WooCommerce. I have read the docs page but I don’t know what it means or wants me to do.

Is there a video that SHOWS you step-by-step how to add Sezzle? I watched the ones for the widget in the footer. I added the custom HTML. What am I missing??
