With the 1.20 change of check pulse to a continous action, there is no way to trigger the "poke" animation previously used by the action. Lots of players have been using the poke as a fun interaction thing, and this is no longer possible due to the change.
My proposal is simple - put the old animation on the emote wheel as a "Poke" with no gameplay action involved. (And have it possible to keybind...)
