As of last year we have support for alt-text on images, which is great! (see https://blog.twitter.com/2016/accessible-images-for-everyone ).
However, as far as I can tell this feature isn’t available for Direct Messages? Cards that I send also don’t seem to be picked up when I view them in a DM chat.
(when composing tweets, I can add a description which renders as alt-text. DMs don’t allow to add a description)
Am I missing something, or is there a place that I can request this feature?
