How does one handle multiple Sidekiq queues on hatchbox.io deployment?

In reference to the ActionMailer documentation stating Sidekiq should be started to listen on the mailer queue, how does one ensure the hatchbox deployment handles this?

In the documentation it states we need the mailers queue to be listened for specifically:
bundle exec sidekiq -q default -q mailers

Hey Aaron,

You just put the queues in your config/sidekiq.yml file. 👍
