Resolves a share link URL segment — the part after /s/ in a share
link like https://example.wistia.com/s/summer-sale — to the share
link and the media it points to, including the media's hashed ID.

The identifier may be the share link's hashed ID or its custom slug.
Historical slugs that were later changed still resolve to the link.

Tokens with the "Act with a team member's permissions" permission

made with such a token are authorized using the permissions of the
contact assigned to the token.
