Require the customer to reserve before adding to cart

[error401]

I use the bookeasy application so that customers can make a reservation. The problem I encounter is that in the collection of all my services, customers have the possibility of booking without taking a date and time. I would like them to be obliged to take date and time before adding to cart, FYI I use the Refresh theme

Require customers to select a date and time before adding to the cart in the Bookeasy application with the Refresh theme, configure Bookeasy settings to make date and time selection mandatory. Adjust the product page template or consult with a developer for customization if necessary.
