1. Is this request related to a challenge you're experiencing? Tell me about your story.

I'm looking for a rag repository platform that supports API calls, and I found this feature available in dify's congeneric product fastgpt (https://doc.fastgpt.cn/docs/development/openapi/dataset/#%E6%90%9C%E7%B4%A2%E6%B5%8B%E8%AF%95). I didn't find this feature in dify's API documentation (https://docs.dify.ai/guides/knowledge-base/maintain-dataset-via-api).
