Question about selling a component on Marketplace

Hi,
I am trying to create a component to sell but have a question.
When creating the component in creator space, Framer is asking me to provide a link to payment service like Lemon Squeezy. Does this mean I need to first create a product on Lemon Squeezy using the Remix Link and then add that link here?

Or this this totally optional and I can leave this blank?

Thanks for your help.
