Introduce a notification system within the main embed UI, particularly integrated into the authbar, to alert users of new interactions. The initial version (v1) will focus on simple but essential notification types, including alerts for replies to user comments and invitations to participate in other SaySo engagements. Future expansions may include notifications like reminders to complete an action after a period of inactivity, and prompts for anonymous users to complete their registration for a more personalized experience. This feature aims to keep users engaged and informed without needing to leave the main interaction interface.
