How to get cacheInstanceId for current configuration

Summary:

We have a custom APEX application integrated within the Configuration section of the CPQ model configuration layout. Users can select products on the APEX screen and then click an action to send the product information back to CPQ. To retrieve data relevant to the user's current configuration session, we need to first pass the current session's `cacheInstanceId` to APEX. This will enable APEX to trigger the update configuration API and return the results to the correct configuration session.
