The new item from 1.21 to claim the reward in achievements is not there

8 days ago when Tricky Trials of 1.21 was released, you launched the new items in the dressing room that are for a limited time to claim. When I got into the gloves there was an epic item that is Charged Gauntlet, it was to obtain achievements so I looked with excitement to know how to obtain and only the new Tricky Trials achievements came out without rewards. Thank you very much Happy Tricky Trials and Happy 15th anniversary.  

Watch two full test videos please because you can't send me just one full test video.
