How to use the pixi-filters.AsciiFilter function in pixi-filters

const bunny = new PIXI.Sprite(PIXI.loader.resources.bunny.texture);
            bunny.x = (i % 5) * 40;
            bunny.y = Math.floor(i / 5) * 40;
            bunniesContainer.addChild(bunny);
        }

        text.position.set(bunniesContainer.width / 2, 0);

        bunniesContainer.hitArea = new PIXI.Rectangle(0, 0, bunniesContainer.width, bunniesContainer.height);

        this.filteredBunnies.x = this.app.initialWidth - this.filteredBunnies.width - 10;
        this.filteredBunnies.y = this.app.initialHeight - this.filteredBunnies.height;

        // Filters
        const filters = [
            new AsciiFilter(),
            new CRTFilter(),
            new GlowFilter(),
            new OldFilmFilter(),
            new ShockwaveFilter(new PIXI.Point(bunniesContainer.width / 2, bunniesContainer.height / 2)),
            new OutlineFilter(1, 0xFF0000),
        ];
    }
