 And this time, just to show again that by using `back_populates` **SQLModel** (actually SQLAlchemy) takes care of connecting the models by their relationships, even though we performed the operation from the `hero_spider_boy` object (modifying `hero_spider_boy.teams`), we are adding `team_z_force` to the **session**.
