Question About Affiliates Pro (WooCommerce)

Buying a website for my client and I’m on the final step, he would like me to add an affiliate program so that his users can apply for his affiliate program and when they use their link to the product, they earn $5 commission into their account that he will pay out.

I’ve been using the plugin Affiliates Pro (Link: https://www.itthinx.com/plugins/affiliates-woocommerce/ ) and they have a detailed documentation that I’ve gone through many times but I can’t seem to figure this out.

Has anyone found another solution to this, or know why I can’t figure out how to do it? I’m sure this plugin (hopefully) can preform this function (as it was $60…) but could anyone help me or explain how to do this? thanks
