Hello Need to add the functionality of "Notify me when available" to a Sylius Store as follows In case the customer knows the link to a product whose all variants are out of stock show a text box to enter the email once the product (any of its variants) is back in stock , the customer will receive an email notifying them that the items are back in stock For the admin , once the customer subscribes to a product, they will be added to a customer group having the same name as the product Once the stock of the product is added, an email will be triggered to the customers of that group
