amazon music offline on apple watch

Hi! On Apple Store, version 22.15.11 of Amazon Music clearly states and shows that Offline playback on Apple Watch is now possible! Should be great news! But it’s not showing any of the DOWNLOAD either OFFLINE Mode option on my Apple Watch. How can I activate this MUST HAVE option?
