Playing "idle" sequencer in game mode with widget blueprint

Hello.
I’m trying to play multiple sequencers in game mode with widget blueprint.
For example when pressing button A, sequencer A with the character is greeting is played.
The image is my current level blue print. Pressing buttons works well.

But how can I play “idle” sequencer in game mode?
I want to playing idle sequencer as soon as entering game mode, not after pressing the button.

Help?
