        This returns a JWT token usable for submitting feedback.

        You should request a token, ***if (and only if) a user is on a feedback page***


        As a rudimentary way of rate-limiting feedback, this endpoint returns a token.

        To post feedback, you will need this token.


        Tokens gain validity after 5s, and are invalid after 12h of being issued.

        They are not refreshable, and are only valid for one usage.
