Which are types of predefined standard events that the TikTok Pixel measures? (Select 2)

The TikTok Pixel automatically tracks several standard events that are common across e-commerce and other online businesses. "Add to Cart" is a crucial event for understanding user intent and optimizing for purchases, as it indicates a strong interest in a product. "Place an Order" (often referred to as "Complete Payment" or "Purchase") is the ultimate conversion event, signifying a successful transaction. These predefined events allow advertisers to easily set up tracking and optimization without custom coding. "Unsubscribe" and "Click to Call" are not standard predefined events tracked by the TikTok Pixel; while they can be tracked as custom events, they are not part of the default standard event list.
