Mark specified inbox message IDs, or explicitly all current inbox messages, as read. Changes read status only; does not read, summarize or triage the content.

Free. This one only touches this instance's own storage, so there is nothing to charge for.

Runs on Mail — Send and receive email.

Arguments
