Can't export all messages

Hi, I'm trying to export messages from personal chat (not team).
I opened bash and used ``keybase chat api <<< '{ "method": "read", "params": { "options": {"channel": {"name": "username1,username2"}, "pagination": { "num": 5000 } } } }'`` However this still only pulls last 1000 messages, not 5000. I've also tried without pagination number and then using next but that displays 0 more messages and writes last param as true.

So how do i dump the entire conversation?

Start by reproducing the `keybase chat api` read request from the issue against a personal conversation, with and without `pagination.num` and `next`. Trace how the chat API handles pagination and verify that a completed export returns all available messages rather than stopping at 1,000.
