@alicam unfortunately I’m not able to share the plugin at this time (it’s for my job).
The plugin, at the moment, is just a native Gutenberg block called “Row”. I created it following this tutorial for making a nested block. It’s essentially just a wrapper div with the <InnerBlock>
inside of it. Sorry I can’t be more helpful!
