Grant distributors access to token data.

Enable access to token data for distributors by setting the token to publishable. This endpoint allows token owners to make their token data available to authorized distributors, enabling them to access and use the token's information for distribution purposes.
When a token is marked as publishable, it becomes visible to distributors in the system, allowing them to access the token's metadata, properties, and other relevant information needed for distribution workflows.
Access level: Token owner only.
