Correct Way to Fetch Unread / Unseen messages of a Folder?

[Dastano]

Hey,

I built a Support Ticket System, which queries Messages like: $folder->query()->unseen()->get();

However, it seems that it took all the emails read/unread and returned them. So I am curious if this is an Issue we should monitor or if I did something wrong.

(We use Google Workspace for our emails and fetch emails via OAuth)
