Thanks for your answers :)

Known limitation with RSC & client component. Please see this mention.

Only Component Fixtures fixtures can be exported from a fixture module with the 'use client' descriptor. That's because Client fixture modules are passed as is to the Server render tree and their exports are expected to be components by design. While Node Fixtures and Multi-Fixtures cannot be used in Client fixtures, all Cosmos fixture formats are supported in Server fixtures.

So if your fixture does indeed need to be a client component (ie. use "use client") you can change the export to

export default () => <Button disabled>Click me</Button>;

Otherwise remove the "use client" directive and the fixture will run as a server component and can export any Cosmos fixture format.

You need to export as below and "use client"
export default () => Click Me or
export default ButtonDummy = () => {
return Click Me
};
