Is your feature request related to a problem? Please describe.
Hosts dynaically add and remove call members and using a waiting room system.
When I add a call member the newly added call user receives the 'call.member_added' event message via the websocket.
But I also have to execute call.get() to refresh OWN_CAPABILITIES of the user to test that the user can now join a call to refresh the UI 'Join/Leave' button.
I utilise 'useHasPermissions' hook and this is stale until I execute call.get(), which I am now doing on 'call.member_*' events if event.members has client user reference.

Describe the solution you'd like
When sending call.member_added WS message include OWN_CAPABILITIES if the user is the client user, and
refresh the internal state of the call.
Maybe this triggers a useHasPermissions re-render, or you implement a new useOwnCapabilities() hook that triggers on change.

Describe alternatives you've considered
