Short answer: You can list advertisers in TikTok Lead Gen by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the TikTok Lead Gen List Advertisers action to a workflow, map its 0 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.
