I'm sorry, but the knowledge sources do not contain enough information to confirm the current availability or visibility of the "ContactsWebAnalytics" and "ProductsWebAnalytics" (Incremental) experimental streams in the HubSpot source connector's schema mapping in Airbyte OSS. The changelog you referenced does mention these streams as experimental, but there are no details about their activation, required scopes, or troubleshooting steps for making them appear in the schema mapping UI. There is also no documentation in the provided sources about enabling experimental streams or specific issues with their visibility after adding all necessary scopes or creating a new source with experimental streams enabled. If you have already ensured that all required OAuth scopes are granted and have enabled experimental streams in the connector settings, but still do not see these streams, it may be a limitation or a current issue with the connector that is not documented in the available knowledge sources. You may want to check for open issues or discussions in the Airbyte GitHub repository or community forums for more up-to-date troubleshooting steps or to report your experience. If you need further assistance, I recommend reaching out on the [Airbyte community forums](
https://discuss.airbyte.io/) or checking the [HubSpot source connector documentation](
https://docs.airbyte.com/integrations/sources/hubspot/) for any recent updates.
