Delete a reaction (Legacy)

**Deprecation Notice:** This endpoint route is deprecated and will be removed from the Reactions API. We recommend migrating your existing code to use the new delete reactions endpoints. For more information, see this [blog post](https://developer.github.com/changes/2020-02-26-new-delete-reactions-endpoints/). OAuth access tokens require the `write:discussion` [scope](https://docs.github.com/[email protected]/apps/building-oauth-apps/understanding-scopes-for-oauth-apps/), when deleting a [team discussion](https://docs.github.com/[email protected]/rest/reference/teams#discussions) or [team discussion comment](https://docs.github.com/[email protected]/rest/reference/teams#discussion-comments).
