How do I update the link to the correct link in Fin?

I queried Fin to answer a question from one of our blog posts. While Fin did pull from our blog posts, he pulled an inactive link that resulted in a 404 error. I found the correct link but I don’t know how to correct in Fin. Can someone advise, please?

For example: 

Say Fin pulled www.company.com/blog123

However, that resulted in the 404 error. 

Fin should have pulled www.company.com/blogabc

How do I update the link in Fin? 

Thank you in advance!
