[JackyW83]

In case if multiple attendees have empty email, the second one won't show in search result by

but now it skips the attendee if it has an email, right?

[JackyW83]

No. If user has email, he/she only skip when this.alreadyInvitedEmails.includes(email) === true, and skip all users don't have email.
I updated the condition check order in latest commit, maybe this looks more intuitive.

 if (email && this.alreadyInvitedEmails.includes(email)) {
	return
 }

In country like China, a lot of people don't have email, so updated this :)

Squash your commits into a single one and rebase to latest main done

Logic sounds good, didn't test
