Hook into Jetpacks Publicize without using a post type

Question

I have a plugin that allows users to power small amounts of data to thier sites. I don't use a custom post type for this but I would like to use Jetpack's publicize to publish to the sites connected social media.

Theres plenty in the jetpack documentation about adding it to a custom post type which doesn't apply in this case.

Is there an action I can call to publicize a message from in my plugin? e.g.

do_action('publicize_message', $message);
