See Particle node in Blender 2.91 Alpha how to put objects in the particles.

Good, my query is that I am trying to match an object in the particles with the nodes (like in the old system, you selected Object and clicked on the object), but I don't know what node it is and well, try a shape in the node " execute "but the initial balls still appear and not the object that is the monkey. Can you send me an image of what the node arrangement would look like in this new Particle System? Thank you!! :)
