Flashing Unit frames

[vale bridge]

Hello!
I'm trying to get my party and raid frames to flash when rejuvenation needs re-applying.
I've got the aura to flash with a pixel glow when rejuv has less than 5 seconds left on the player, but it disappears after rejuvenation has run out.

Any support before I yeet myself out of the window?
Thanks

You need separate triggers for the buff being found but low remaining duration and for missing.

Since you're cloning for anchoing to frames you'll probably just want to do this with separate Auras
