mux.jwt.signPlaybackId returns undefined - JWT helpers not present in library

[billyberkouwer]

Following the API docs, it suggests generating a JWT using mux-node-sdk's helper functions, however the examples do not work.

const token = await mux.jwt.signPlaybackId(playbackId, { ...baseOptions, type: 'video' });

Returns:

TypeError: Cannot read properties of undefined (reading 'signPlaybackId')
