I am working on meteor-angular and trying to track new user login and logout changes within a single component. I have attempted to subscribe to userData in the component's initialization, but it does not seem to detect when the user logs in or out. Interestingly, if I refresh the page, it detects the user details. Is there anything else that can be utilized within the component to handle login/logout or other user events? The goal is to dynamically update user roles based on different users within the component and reflect those changes accordingly. Thank you.
