Niagara Initialize Mesh Reproduction Sprite shows on viewport but does not show in game

I am following this Unreal Engine tutorial:

When the video does it (11:05) the particles show in game but when i play the particles do not show in game. Did the video miss something?

Check images attached.

Thank you.

I realised that for the system to be visible you need to add it as a component on an actor.

Just dragging the system inside game wont make it visible on play
