hm, it's not only "Stop casting", one could control the volume and potentially
do other stuff. Should we ask Rachel to update the mocks with a better wording?
ok to land like this (modulo i18n) but we probably want to correct the wording
later on.

Acknowledged. I'll reach out to Rachel about this.
