Entra External ID with Apple ID, Microsoft?

I would like to use Entra External ID with Apple ID and also Microsoft (eg Hotmail). In Azure B2C, Apple ID integration was possible. But in Entra External ID only Google and Facebook are available. Is this an oversight or just not implemented yet? Also can I not configure something like Microsoft Hotmail for Identity Provider? While I can invite a user, it will force them to create a password. Can it not just use their Apple or Microsoft identity without needing them to create a password in the Entra External ID system? What am I missing?
