Code snippets

const client = new Voice.Client({
      host: process.env.RELAY_HOST || 'relay.swire.io',
      project: process.env.RELAY_PROJECT as string,
      token: process.env.RELAY_TOKEN as string,
      topics: [process.env.VOICE_CONTEXT as string],
      // contexts: [process.env.VOICE_CONTEXT as string],
})

When both topics and contexts are passed, topics will have more priority.
