I have setup a store which is still in trial mode and installed bookthatapp. I tried to setup bookthatapp for "capturing a booking date" (first option in the installation instructions). Although I did click on the "Install this snippet for me" the calendar is not showing on the product page when I select the product variant.
I can activate and inactivate the floating bar but that's not the option I want. The documentation page shows the code changes that needs to be done and where to position them in the file ( ('booking-form.liquid'). How do I access that file?
My question what do I need to do to see the date picker on my website (something similar with this demo site http://pragmaticinsights.myshopify.com/collections/product-rentals/products/boat-rental)
