If you choose to use the "Interactive Map display" feature of Digiloop Pickup & Delivery, the map would be shown on your Cart page.
At the moment, there is no pre-existing possibility to add the map to the Checkout page and it requires a custom solution.
If you wish to have the map shown in the Checkout page, please keep in mind that it would be required to have a Shopify Plus plan, which can be discussed with Shopify Support.
Once you have the Shopify Plus plan, get in touch with us for a custom integration via e-mail at [email protected] or via chat.
