How can I access a assets (animation sequence) using scripting in Spark AR studio

Question

I'm trying to change the current frame of an animation sequence using a script in JS and I can't find the equivalent of Scene.root.find.... of assets... I'm trying to create a "Which ____ are you?" and I make the code for the roll an image but I don't know how to access it using scripts?

If I get it right, this will help you.

const Materials = require('Materials');
const mat = Materials.get('matName');
// set your number here, or an animation
mat.diffuse.currentFrame = 1;

UPD 8 May 2021: Now you should use async methods:

const M = require("Materials"); 
const D = require("Diagnostics");
(async function () {
    const mat = await M.findFirst("material0");
    const diff = await mat.getDiffuse();
    diff.currentFrame = 1;
})();
