Remove a Product Hunt launch upvote

Output
hasVoted requiredWhether the account still holds an upvote after the run. False on success.
launchUrl requiredaccount_used requiredHandle of the account whose vote was withdrawn, read from the signed-in session rather than assumed.

verified_on_page requiredTrue when Product Hunt's own response confirmed the launch is no longer upvoted.
postId optionalProduct Hunt's numeric id for the launch.
scoreAfter optionalScore Product Hunt reported with the change. Other people vote continuously, so this is their number at that instant, not necessarily scoreBefore - 1.
scoreBefore optionalScore shown on the control before the change. Read from the rendered figure, so it can lag other people's votes by moments.
FAQ
Get Product Hunt product
Read a Product Hunt product page and return its profile: name, tagline, full description, the outbound website link, the categories it is listed under, its review rating and review count, how many times it has launched, its makers with their Product Hunt profiles, and any Top Product or Golden Kitty awards. Accepts either the product slug or a full Product Hunt product URL. Follower counts are returned exactly as the page displays them (Product Hunt rounds them, e.g. "18K") alongside a numeric approximation. An unknown product is reported as such rather than returned as an empty record.
Get Product Hunt launch comments
Read the comment thread on a Product Hunt launch. Returns each comment with its author (name, handle, profile id and the product they are credited to), the text, its upvote count, when it was posted, whether it is pinned, and how deeply it is nested so replies stay attached to what they answer. Accepts a full launch URL or a "product/launch" slug pair. Product Hunt's headline comment tally on a launch counts more items than the thread actually renders, so both numbers are returned side by side rather than presenting the visible ones as the complete set. An unknown launch is reported as such.
Product Hunt login (Google SSO)
Log into Product Hunt with its Google sign-in option, handling the Google account chooser and consent screen. Returns straight away if you are already signed in, and reports the Product Hunt handle, display name and user id. Optionally pass which Google account to use. Needs a browser already signed in to Google and a Google account that already has a Product Hunt account.
