callInvitationURL != joinInvitationURL

**Describe the bug; what happened?**

I'm trying to use the pre-built bundle to get CallWithChatComposite working. When I was passing in callInvitationURL as the documentation was suggesting it wasn't working.

Then I looked at the source code and see a reference to joinInvitationURL instead, which does work.

I think these two names/the documentation needs clearing up?

Compare the documented callInvitationURL with the source reference to joinInvitationURL in the pre-built CallWithChatComposite bundle. Trace which name is accepted and update the relevant documentation or naming so the documented usage matches the working interface; done means the two references are consistent and the documented option works.
