**Describe the requested icon(s)**

Stylized like your other brand logos, I'd like to see a Diigo Logo icon.

<!-- Explain the icon(s) you'd like to see, and potential use-cases. Be specific. Do not say "etc..." unless it is unambiguous what that means. -->

**References**

An icon for the [Diigo](https://www.diigo.com/) logo, I'm using your icons to stylize [Instructure's Canvas](https://www.instructure.com/canvas?domain=canvas) and they have the ability to connect a Diigo account to your Canvas. It's great that there's already a Google Drive and Skype icon, but for the Diigo icon, I'm using a placeholder right now.

<!-- If applicable, add screenshots, examples, or references to the icon(s) in other sets. -->

**Additional context**
Placeholder I'm using:

Diigo logo (not stylized to look like Phosphor Icons):
