Twitter – add ALT-text of media files to metadata

[aleksusklim]

Twitter allows to set descriptions for images and video in tweets:

Length limit is 1000 characters per each media:

When displayed, the media will have "ALT" popup, which shows this description when clicked:

Will it be possible to assign such alt-text to a metadata field (per media, for "prepare"-event and alike)?
By inspecting server response in browser, I see it in globalObjects.tweets[id].extended_entities.media[i].ext_alt_text or in *.itemContent.tweet_results.result.legacy.extended_entities.media[i].ext_alt_text, hope that helps.
