OAuth2 using Rest

Heyo!

Does someone have a working way for OAuth2 using REST? I am struggling to get it to work, for example using the discord oauth, I am getting:

Request header field x-appwrite-response-format is not allowed by Access-Control-Allow-Headers in preflight response.

you're supposed to redirect the user to that URL

This is what the docs say: https://appwrite.io/docs/references/cloud/client-rest/account#createOAuth2Session

So that's exactly what I am doing

There's also nothing else in the docs about this, it's very empty, so I don't know where to send the user to

tip: refer to the SDKs

https://github.com/appwrite/sdk-for-web/blob/bf13f876b75ff590f4b0921770cf6fc027d4622a/src/services/account.ts#L736

it doesn't say enough for me though, that's what the docs say and I am doing, also this is also outdated: https://appwrite.io/docs/products/auth/oauth2 account.createSession doesn't seem to exist :/
