Riftui - Flaring Power & Wild Growth

I want to show when our Archond cast FLARING POWER with the 15 seconds counting down (and if possible the 5 minutes cooldown counting down)
and the same, when our Chloros are casting WILD GROWTH with the 12 seconds counting down (and if possible the 1 minute cooldown counting down)

I tried using myUI:
"Debuffs cast bei Unit & Others on Target" (Others & Unit at the top and Target left)
and
"Buffs cast bei Unit & Others on Target" (Others & Unit at the top and Target left)
and
made a Whitelist which contains only "Wildwuchs" (Wild Growth) and "Kraftausbreitung" (Flaring Power).

But it shows neither. :-(

I didn't get it to work with nkRebuff or KaruulAlert. Maybe I am just too stupid :-(

Is there a simple addon, that I didn't see yet? Or can someone write one, pleeeeaaaase :)
