Cowork or code for creating animated explainer videos?

I've seen clips of people making really cool animated videos with 5.5. I want to create a cool explainer video of our multi step AI writing process for a client. I want it to pull logos from sites, used client head shots to make a cartoon or claymation style video. Would that be done in code or cowork. I assume it would involve JavaScript. Which is why I thought it would have to be done in code. Any recommendations would be greatly appreciated.
