Do you have any news, @medikoo? I'd like to present the plugin at the next Codemotion in Milan in November '23.

@franc-liuzzi thanks for adding your plugin, still I'm no longer with Serverless Inc, and I don't have any rights to manage any contributions here. Please follow up with @Mmarzex or @ac360, as far as I know they manage community contributions at this point

Thanks @medikoo.

So, @Mmarzex and @ac360 is there any news about my contribution?
