Hello Anshul,
To view the list of orders of a logged in user, you'll need to create a menu. If you're using Squick demo, it's already present in the footer menu. If you want to create a new menu for list view of orders, you can create it from Joomla administrator > Menus > Main Menu. Click on the new button to create a new menu item. Select in Menu item type Sellacious > Orders. Save this menu, after filling other necessary details.
I hope this helps.
Thank You
-Team Sellacious
