People access Share and Action extensions by tapping the Action button in an app. In the activity view controller displayed by the Action button, Action extensions are listed in the bottom row and Share extensions are listed above them. People can use the More buttons to manage the Share and Action extensions that are displayed in the activity view controller shown here.

A Share or Action extension typically takes as input the content in the user’s current context. While reading an article in Safari, for example, a user might tap the Action button and use a Share extension to post the article to a sharing website or use an Action extension to view a translation of the article.
