how to implement animation in wayland since window move request is not supported?

[Barry Song]

sorry for the ascii text picture can't show well in gmail. the
animation is pretty much like
 drop-down terminal - Yakuake
https://kde.org/applications/system/yakuake/

when you push a key, the Yakuake will move out from the top.
