Bookmarklet that presents a UI on top of the Twitch Video Producer page to retrieve data for videos en masse.

Go to the Twitch Video Producer
Click the bookmarklet to open the UI
Optionally specify a minimum date to limit video data retrieval:
- If you've already run this and have data stored, find the publishedAt value for the most recent video and paste its value into the text box
- Otherwise type a date in YYYY-MM-DD format into the text box
Specify which types of videos you're interested in
Click on "Get data"
- Clicking the button should disable it while it runs; if nothing happens, check your date format
After "Get Data" completes, the "Copy data" button will become enabled for retrieving data
- "Copy data" will copy the JSON data twitch returned (with a few fields pruned) to the clipboard so you can paste and save it

A few notes on the data returned:

game may be absent if no game was set on the stream, or if the game is no longer listed on Twitch
deletedAt will contain a future date for past broadcasts, indicating when they expire
If you have any videos processing at the time you run the bookmarklet, those videos will have a lengthSeconds of 0 and a status of "UNPROCESSED"
The bookmarklet excludes muteInfo (related to muted segments of the video) and thumbnailURLs (which contains both the autogenerated and any custom thumbnail URL; previewThumbnailURL already reflects the selected one, with placeholders for width and height)

Uses the same GraphQL operation used by the video producer list for retrieving its data
Changes the page filter in order to pick up headers needed to make the requests
Does not send data anywhere other than Twitch's GraphQL endpoint
