Adding live display of product availability

[Unsunggod]

Hey Shopify team! I've been searching a way to find how to add "In stock, ready to ship" with the green flashing light as seen below, also I'd like to have added "Free shipping & returns" & "Secure checkout" as seen below in basically the same format, clean, tidy with the icons on the left side.

Is this an app to add or website dev work? Thank you kindly for your help 🙂
