Stripe links in basic plan

I put some Stripe payment links on my site but they don’t work. I then realised this is probably because i have a basic plan and would need an e-commerce plan, is this right? or am i doing something wrong?

i do not really envisage these ‘product’ being a main earner so i was hoping not to have to upgrade my plan.
