Stuck at the very start

Hi there !
I’m solo learning sound implementation, but I have absolutely 0 knowledge in Unity.
I tried to follow the Karting Game tutorial but I’m stuck at point 3.2: precisely there:

  • Select the GameManager/GameHUD object.
  • Click the context menu icon on the Feedback Flash HUD component.
  • Select Edit Script to open the script file in your default code editor.

What is the context menu icon, where is it ? Nor can I find the Edit Script Option.

Unity’s context menu icons are marked with an ellipsis rotated ninety degrees. The first screenshot in section 3.2 features a red box drawn around the context menu icon of an Audio Listener component. Look for a similar icon on the Feedback Flash HUD object.
