Hello, @IP,
First of all, you have to create such a section using the Static Block and then you have to set that static block in the sidebar from Appearance >> Widgets >> Single Product Page Sidebar: https://postimg.cc/6TC4BfzQ after that you can set it to a Single product page under the sidebar from XStore >> Theme Settings >> WooCommerce >> Single Product Builder >> Layout and choose that sidebar: https://postimg.cc/MM9RVy3B
