Set these under components.Sender in your token file, or pass them to ThemeScope to change one region of the page. The same tokens style Sender.Header and Sender.Switch.
Component Tokens
Ant Design X's own Sender tokens, with the values its default seed produces. Set one and it applies to every Sender under the provider.
Global Tokens
The global tokens Sender reads. Set one under components.Sender to change it for Sender only, or at the top level to change every component.
