Electron platform already exists trying to install

Describe the bug

Unable to install

To Reproduce Steps to reproduce the behavior: Existing Ionic React app with some capacitor plugins for web.

Follow instructions at:

https://capacitor-community.github.io/electron/docs/gettingstarted

So using yarn so do yarn @capacitor-community/electron

This adds:

"@capacitor-community/electron": "^4.1.2",

To my dependencies in package.json.

Then do:

npx cap add @capacitor-community/electron

But hit:

npx cap add @capacitor-community/electron

Ok, hmm, maybe I did this in the past, git reset, try try just the npx cap add @capacitor-community/electron command but get:

npx cap add @capacitor-community/electron
[error] Platform @capacitor-community/electron not found.

So I have a Schrödinger's electron installation somehow? It is installed and not installed at the same time!? Expected behavior

Be able to install
