We need to fetch open conversation through below code while you implement Add your delegate to the core client object
Android: https://developer.salesforce.com/docs/service/messaging-in-app/guide/android-user-verification.html
IOS: https://developer.salesforce.com/docs/service/messaging-in-app/guide/ios-user-verification.html

>>We can use the force flag as documented to ensure the request is being made over the network and not just from the local database:

IOS:
https://salesforce-async-messaging.github.io/messaging-in-app-ios/Protocols/SMICoreClient.html#/c:objc(pl)SMICoreClient(im)conversationsWithLimit:olderThanConversation:completion

 
abstract suspend fun conversations(    limit: Int,
    olderThanConversation: Conversation? = null,
    conversationId: UUID? = null,
    forceRefresh: Boolean = false
): Result<List<Conversation>>

 >>forceRefresh: Forces the requested data to be refreshed over the network when set to true. Otherwise, the requested data is fetched from the local cache and only refreshed over the network if no results are found locally. Default value is false.

For Messaging for WEB, we no need to create/fetch conversatio because JWT token has Sub of MessagingEndUser which automatically fetches open conversation of MessagingEndUser
