How do I use App check with custom provider?

[artrayd]

I need to use the Turnstile provider instead of reCaptcha.

How do I do that? Is it supported? Will this code work?

appCheck: {
  debug: process.env.NODE_ENV !== 'production',
  isTokenAutoRefreshEnabled: true,
  provider: 'Turnstile',
  key: 'turnstile-key',
},

For Turnstile, I used this module:
https://github.com/nuxt-modules/turnstile

Here is a guide from the Firebase extension, but it doesn't mention the Nuxt 3 module
