Based on the information available in the knowledge sources, "Powered by Airbyte" does support the use of connectors, but there is no specific mention of whether it provides an OAuth journey for connectors. However, from the general information about OAuth support in Airbyte, we know that OAuth flows are primarily available in Airbyte Cloud. For the open-source version, it is possible to use OAuth credentials if you have a process to generate the necessary values manually. For more detailed information about "Powered by Airbyte" and its capabilities, you can refer to the [Powered by Airbyte](
