Hello all, It's not clear to me what happens if I update an existing knowledge base with a new file. Will the content of the old file be removed from the existing knowledge base and be replaced with the new one, or will the new one be added to along with the old one. Here's an example: I have

file_A

and

file_B

. I create a knowledge base with `file_A`by

POST

to

https://api.vapi.ai/knowledge-base

with

fileIds: ["file_A_id"]

. So now I have my knowledgebase with the contents of

file_A

. Now I decide to replace

file_A

with

file_B

. So I upload

file_B

, delete

file_A

and call

PATCH

to

https://api.vapi.ai/knowledge-base/old_knowledge_id

with

fileIds: ["file_B_id"]

. My questions are: 1. Does the knowledgebase now has the contents of both files, or are the contents of

file_A

been removed? 2. If the first is the case, then how should I handle the case where a user decides to replace (and/or remove) some files? Should I remove the old knowledge base entirely and create a new one?
