The use of the Mighty Button as a social button is very regular and you will probably use it many times. Due to its usefulness, it could even be a larger entity as an independent interactivity, but since its usage is very similar to the one of a button, it has ended up being a specific configuration of the Mighty Button.
The Social Share button enables to share the content in which it is located –that is, the interactive video it is part of– on any compatible social media. To configure it, simply access the Properties panel and on the Action submenu, choose Social Share. According to the social media you set up as the destination of the button, the specific parameters will vary. It is not indispensable that you fill in all fields, but it is recommendable since it will affect the aspect shared content will have, as well as the information about the link.
Keep also in mind that each social media requires a different button that you will have to create, and you will have to import them previously to the Media library.
