Create a Wish List on our Gin App

As a user signed-in,
I would like to add a (or several) Gin that is not to sell yet to a wish list,
in order to be notified when it will be available to order (a price is defined).

How can we add an option to the detail page of the Gin, related to the user that allows him to do so?

Tkx community! :wink:

I would suggest a form button for the user to submit interest along with their email address.
