Should I use delta-time to move my camera?

Ashley's 2017 article on delta-time says:

Don't forget behaviors already use dt. If you use behaviors to control all motion in your game, you don't have to worry about dt at all!

So, can I ignore delta-time when using the lerp function to position a sprite with the ScrollTo behavior? For context, see the comments in my code below:

const lerp = (start, stop, amount) => amount * (stop - start) + start;

export default class Game {
 #runtime;
 #camera;
 #player;

 start(runtime) {
 this.#runtime = runtime;
 this.#camera = this.#runtime.objects.Camera.getFirstPickedInstance();
 this.#player = this.#runtime.objects.Player.getFirstPickedInstance();
 this.#runtime.addEventListener('tick', () => this.#onTick());
 }

 #onTick() {
 // Do I need `this.#runtime.dt` here?
 // Or, does the scrollTo behavior already use it?
 const amount = 0.3 * this.#runtime.dt;
 // Move the camera to the player's position using lerp.
 this.#camera.x = lerp(this.#camera.x, this.#player.x, amount);
 this.#camera.y = lerp(this.#camera.y, this.#player.y, amount);
 }
}

Just for clarity, this.#runtime.objects.Camera.getFirstPickedInstance() is a sprite with the scrollTo behavior enabled.

I don't know how you read the article. There is this paragraph here:

It's also a good way to test you have used dt correctly. If you have used it correctly, setting the time scale to 0 will stop everything in the game. If you have not used it correctly, some objects might continue to move, even though the game is supposed to be paused! In that case you can check how those objects are moved, and make sure you are using dt properly.

Thanks for your reply! Is it possible to set the time scale to 0 for testing without using an event sheet? It seems like it's not based on this discussion.
