What does the List Avatars action do in Synthesia?
Returns the avatars available in your Synthesia workspace, including stock avatars and any custom personal avatars. Use it to render an avatar picker before generating.
What inputs does List Avatars require?
List Avatars has no required inputs. Sensible defaults are applied if you leave fields blank.
