Spectral: How to correctly override oas3-unused-component targetting components.schemas.$ref?

I apologize if this is the wrong channel for this. I could not find anything explicitly related to spectral in this discord, though the spectral github support section links to this https://github.com/stoplightio/spectral#ℹ%EF%B8%8F-support

Here is an edited version of my root OAS file:

openapi: "3.1.0"
servers:
  - url: https://api.com

paths:
  $ref: "paths/_index.yaml"
components:
  schemas: 
    $ref: "schemas/_index.yaml"
tags:
  - name: api-keys

Here is my spectral config file:

extends: ["spectral:oas"]
overrides:
  - files:
      - "main.yaml#components.schemas.$ref"
    rules:
      oas3-unused-component: "off"

Here is the warning I am trying to suppress with the override:

 17:11  warning  oas3-unused-component  Potentially unused component has been detected.  components.schemas.$ref

It does not suppress the warning. I don't understand why.

I'd also like the linter to give more information on which parts of the component it thinks are not being used.
