💬Set Up Your Cart Using These Prompts

Once connected, try asking your AI assistant prompts like:

• "Can you set up my cart with product recommendations?"
• "Can you set up a three-tier reward progress bar at the top of my cart with free shipping at ₹700, a 5% discount at ₹1,799, and a free gift above ₹2,500?"
• "Can you use my store's default font and color theme throughout the cart?"
