It seems that `wp_interactivity_state` function is missing from the [Server Functions](https://developer.wordpress.org/block-editor/reference-guides/interactivity-api/api-reference/#server-functions) section of the API Reference. It should be similar to the [`wp_interactivity_config` section](https://developer.wordpress.org/block-editor/reference-guides/interactivity-api/api-reference/#wp_interactivity_config).
