// EmojiPATCHHandler swagger:operation PATCH /api/v1/admin/custom_emojis/{id} emojiUpdate
//
// Perform admin action on a local or remote emoji known to this instance.
//
// Action performed depends upon the action `type` provided.
//
// `disable`: disable a REMOTE emoji from being used/displayed on this instance. Does not work for local emojis.
//
// `copy`: copy a REMOTE emoji to this instance. When doing this action, a shortcode MUST be provided, and it must
// be unique among emojis already present on this instance. A category MAY be provided, and the copied emoji will then
// be put into the provided category.
//
// `modify`: modify a LOCAL emoji. You can provide a new image for the emoji and/or update the category.
//
// Local emojis cannot be deleted using this endpoint. To delete a local emoji, check DELETE /api/v1/admin/custom_emojis/{id} instead.
