In Gmail, the draft (before send them) are present in the draft folder and if you do them manually they stay in the inbox at the end of the thread. But on n8n they are only present in the draft folder as gmail api require other params to align the draft to stay in the inbox thread conversation. I write some note here: Enhance Gmail Node to Support Threaded Drafts asking for the feature to be added as shuld be relative fast to implement!
