Is there an equivalent to externally_connectable API in Safari like what chrome has ?

Would we always have to inject content script into a webpage in order to communicate from webpage to extension ?
Is there an externally_connectable API approach in Safari just like in chrome ?
externally_connectable isn't currently supported in Safari.

If you could please file a bug at https://feedbackassistant.apple.com explaining why you would like this API - that would be very helpful for us.

Thanks!
