WP Blocks Icon Library in Wordpress Editor

Is it possible to build a Wordpress block with Pinegrow that allows to choose an icon from some library or framework in the Wordpress Editor?

@Jorge at the moment it is not possible to use custom attribute controls. The simplest solution for now is to have a class attribute field that lets user paste in the icon class(es). If the set of icons is limited, you can define a select control with predefined values.

@matjaz Thank you for your explanation.
