Zendesk messaging SDK (iOS/ Android) Clear anonymous user sessions

I have seen many posts about the SDK not being able to clear sessions as web widget does. Want to understand this better.,.

https://support.zendesk.com/hc/es/community/posts/4659977184026-iOS-SDK-Reset-Zendesk-Messaging-History-Change-Channel-Key-Programmatically

Our use case

1. A user logs into our App

2. Opens up Zendesk Messaging (we dont use JWT auth)

3. Creates tickets have conversations etc.

4. In future say the user logs out from our App, in this case I want to clear all the messaging history and all so that if another person logs in to our app, it will be a fresh session.

In one of the post it says even Invalidate was not working.

Please guide me on this
