How to let non-admins use Elements in WordPress?

Hi.
I use the Wordpress Envato Elements plugin and I love it.
https://elements.envato.com/extensions/wordpress/
I could not find out how to give my authors and editors the ability to add photos to posts using Elements plugin. I even tried to install the dedicated user-role-editor plugin “User Role Editor plugin for Wordpress” but could not find out the capability to use envato in there.

did I miss something ?
