I am struggling trying to finish the badge "Lightning Alternatives to JavaScript Buttons" https://trailhead.salesforce.com/modules/lex_javascript_button_migration.

The 3rd unit "Discover Lightning Actions"  https://trailhead.salesforce.com/modules/lex_javascript_button_migration/units/javascript_buttons_to_lightning_actions, has a challenge that ask you to change the component "quickcontact" (installed as per instructions) before you can add the Lightning action on the  Account object.

I got to the point of editing the component using Developer Console, but really don't know what to do next while editing, before I can create the Action button.

Any help would be greatly appreciated.
