If we are talking about the content of the component, then you need to forward the user group inside (Through an array of parameters) and configure caching and output according to this principle. (Indicate which component you are using, standard or your own.) If you need 2 different templates, then there is a built-in functionality for this in the Settings -> Sites -> Custom site settings-> At the bottom of the conditions for displaying templates.
