How can I add a new item to a cached root query that is parameterized - and also has a sub-array?

Help

I have a mutation that returns a new object that I want to add to an array of objects that is part of a graph in a parameterized root query. I have multiple root queries by the same name but have different parameters. I need to add the new “comment” object into comments array within the correct cached “post”. I searched and found apollo-augmented-hooks but I’m not sure how to use it, especially to add it to the array that is within that cached object.

commentsConnection:{"where":{"post":{"id":"05122322-e7e2-412e-9ad1-3013808b89f3"}}}

The “CommentsConnection” object for that key has a __typename and an “edges” array of “CommentEdge”. I want to add a new comment into that “edges” array:

      }
    }
  ],
  "pageInfo": {
    "__typename": "PageInfo",
    "endCursor": "YXJyYXljb25uZWN0aW9uOjI=",
    "hasNextPage": true,
    "hasPreviousPage": false,
    "startCursor": ""
  }
}

I attached a screenshot of my cache for reference.
I’m new to Apollo, so I really appreciate the help!
