When someone tweets with (for example) "please reply via DM", what's the easiest way of sending a direct message back to that user that links to that tweet?
The closest I can find is the option to share the tweet via DM in the share (outbox) menu, but you then have to select whom you want to share it with (and the originator isn't pre-selected) so it's obviously not intended to be a "reply" option.
There doesn't appear to be anything in the ellipsis menu either.
