is the Native Vapi knowledge base using query tool features is still supported or it`s only Trieve i have to use to let the assistant lookup the knowledge base during the call ?

Based on the information I've found, the Native Vapi knowledge base (also called Canonical) is no longer supported. Vapi has migrated from Canonical to Trieve, and you must now use Trieve for knowledge base lookups during calls. According to the [Vapi Changelog](https://docs.vapi.ai/changelog/2024/12/5), "The ability to create, update, and use canonical knowledge bases in your assistant has been removed from the API." Multiple sources confirm that "the old functionality is no longer supported" and you now need to "attach the Knowledge base using API" with Trieve as the provider.

Hey Ramy, the query-based tool for KB is still supported, and it's a recommended solution. Let me know if you require any further help with it.
