Use text in particle emitter?

Phaser 3
1

Hey,
I am trying to use text (instead of image keys) in my particle emitter.

Here is my code:

var emitter1 = this.add.particles("stone").createEmitter({
    x: { min: 50, max: config.width - 50 },
    y: config.height,
    speed: { min: 500, max: 850 },
    angle: { min: -110, max: -80 },
    scale: { start: 0.5, end: 0.1 },
    active: false,
    lifespan: 3000,
    gravityY: 800,
    quantity: 1
});

This creates a nice physics animation, though I am only able to use images. Could I use other objects such as geometry and text?

Thanks.
