Hi, My scenario is - upsert the whole document with optimistic locking control (seqno/ primary term) - I also want to do some conditional update meaning I want to update only when current doc's updatedAt is earlier than what I am providing. I also want to see if I can use external version for this purpose which might have a conflict with seqno/primary term conceptually? Initially what I was thinking is that - using UpdateRequest ( but not using partial update) - using Script to apply conditional write - providing a whole doc to enable Upsert Can we do these using UpdateRequest? or should I do this as a separated steps? checking updatedAt and then try to update? Thank you. (I am using es 7.17.0) ---
