sql query: Need to add Join to query that already has left join

My query is working perfectly. It's gleaning login, email first name and last name from wordpress tables: users and usermeta.

I need to add the field: course_progress from table: wp_wpcw_user_courses using "user_id" to join everything. My issue is that I'm already using "user_id" to join users and usermeta.

Here's my query so far using users and usermeta:

SELECT

                    
					  wp_users.user_login,
					  MAX(CASE WHEN wp_usermeta.meta_key = 'first_name' then wp_usermeta.meta_value ELSE NULL END) as first_name,
                    MAX(CASE WHEN wp_usermeta.meta_key = 'last_name' then wp_usermeta.meta_value ELSE NULL END) as last_name,
					wp_users.user_email
                   

                    FROM wp_users

                    LEFT JOIN wp_usermeta
                    ON wp_users.ID = wp_usermeta.user_id

                    GROUP BY wp_users.user_login ORDER BY 3 asc
