NotFoundError: Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node

```

* Including CMS.init() in App.tsx (as the docs appear to suggest) would make the Decap CMS login form show up within my home page - WRONG: I only want the Decap CMS login to show up when in the /admin route

** Tech Stack **
* React w/ Typescript, built w/ Vite
* react-router-dom
* tailwindcss

**To Reproduce**
Navigate to /admin route

**Expected behavior**
Load the Decap CMS login form

**Screenshots**

**Applicable Versions:**
- Decap CMS version: `decap-cms-app@3.16.0`
- Git provider: `git-gateway`
- Browser version: `Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/151.0.0.0 Safari/537.36`
