The documentation for chips says

onClick - called when this chip is clicked. If null, then this chip will not be interactable,
unless something else handles its input events and updates its state.

but the onClick parameter has a non-null Type

Because it isn't optional it always captures click events which isn't useful for example if a wrapping component is interactable or if you want to implement a custom click handler

This is likely a documentation bug, chips should be clickable, they can be disabled but the onClick parameter should always be provided. Same as in compose.material
