• • Tests

Motivation and Context

When the webchat is embedded inside a VTEX storefront, the store already provides its own native cart UI. Showing the webchat's internal cart navigation buttons (see cart / shopping cart) in this context is redundant and may confuse users by creating a parallel cart flow inside the chat widget.

Summary of Changes

Introduced a context-level boolean flag isInsideVTEXStore, populated once at mount by calling getVtexAccount(). The flag is exposed through ChatContext and consumed across the relevant components:

• ChatContext — imports getVtexAccount, initializes isInsideVTEXStore via a useState lazy initializer, and exposes it to all consumers.
• CounterControls — replaces the direct getVtexAccount() call in isAbleToAddProduct with isInsideVTEXStore from context, removing the dependency on the utility function for the boolean check.
• Header — derives showCartButton = cartTotalItems > 0 && !isInsideVTEXStore and guards the shopping_cart button accordingly.
• ProductCatalog — derives showSeeCartButton = totalItems > 0 && !isInsideVTEXStore and guards the footer "See cart" button.
• ProductDetails — derives showSeeCartButton = totalItems > 0 && !isInsideVTEXStore and guards the "See cart" button inside the quantity > 0 branch.
