   Such requests need to first add support upstream, a patch has been   
   posted in   
   https://lore.kernel.org/linux-bluetooth/20260214215815.26248-1-edo@akse.cloud/   
   but needs first to be accepted.   
      
   Adding accordingly metadata so we can track the progress upstream.   
      
   Regards,
