There are a few third party sites that you can use to get embedded code for Instagram widgets.

One Instagram widget site that works well with our embedded content block is LightWidget.
LightWidget offers both free and paid versions of their Instagram widget services. 

Once you get the embedded code from LightWidget you can use that code on your website by using our embedded content block.

You can follow the instructions on creating an embedded content block here: How do I embed content on my website?
