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

I want to learn how to change Firecrawl API connection.
First, I connected with Firecrawl cloud endpoint.
Now, I built self-hosted one.
I see this self-hosted one works on the other Dify workspace with initial settings.
But I couldn't find how to disable existing Firecrawl settings and re-authenticate.

2. Additional context or comments
