Walkthrough

A filtering condition in the logic for identifying new members not yet part of a specific team was updated. The code previously checked for a match between the id property of team objects in a user's teams array and the group's teamId. This was changed to compare the teamId property of each team object instead. This affects the determination of which users are flagged as new members for invitation email purposes.

Learning: In Cal.com's getUserEventGroups handler refactor (PR #22618), the membershipCount field for team event groups is intentionally set to 0 in the new createTeamEventGroup function, as confirmed by sean-brydon (PR author). This preserves the same behavior as the old implementation that was being refactored, maintaining backward compatibility. While other parts of the codebase may use actual member counts, this specific implementation maintains the previous behavior.

188-188: Excellent bug fix for membership comparison.

This change correctly fixes the team membership comparison. The user.teams array contains Membership objects (due to teams: true in the Prisma query), which have a teamId property, not an id property. The previous comparison team.id === group.teamId would always fail since Membership objects don't have an id field that matches the team's ID, potentially causing all existing team members to receive duplicate invitation emails.
