Multiple firebase projects with multi factor authentication

[BlindDev]

So I have an app that works with multiple firebase projects (prod and dev).
Testers can switch between environments while app is running. FCM and analytics are setup for prod only.
Authentication with password and email link as single factor worked fine with both configurations until we implemented multi factor auth.

It seems like the authentication with reCAPTCHA always points to the [DEFAULT] app and ignores secondary app. When I try to login with secondary config, the first step with email link authentication passed as expected but when I'm trying to resolve second factor I'm getting the following error when reCAPTCHA web page is opened:

[auth/internal-error] An internal error has occurred, please try again.

The mfaResolver contains valid hints:
[{"displayName":"","factorId":"phone","uid":"...","enrollmentDate":"2023-07-04T12:06:23Z"}]

But verifyPhoneNumberWithMultiFactorInfo throws the auth/internal-error so I'm not getting the verificationId

In the logs I see the following output:

10.7.0 - [FirebaseAnalytics][I-ACS023001] Deep Link does not contain valid required params. URL params: {
    "deep_link_id" = "https://<project>.com/__/auth/callback?authType=verifyApp&recaptchaToken=<token>&eventId=lmsbsplysm";
}

So in this link I see the prod project instead of dev

But when I use default prod config it works. And also if I force dev configuration as ['DEFAULT'] it also works fine.

Using firebase 17.4.2.

Am I doing something wrong in my code or the second factor is not supported for multiple firebase apps?

So I assume that this is why it happens:
In the node_modules/@react-native-firebase/auth/ios/RNFBAuth/RNFBAuthModule.m all methods related to MFA use this instance:
FIRPhoneAuthProvider.provider
Meanwhile the phone auth methods use this:
[FIRPhoneAuthProvider providerWithAuth:[FIRAuth authWithApp:firebaseApp]]
I guess this is why the MFA always defaults to whatever is set as ['DEFAULT'] application

I tried to patch this file with setting up provider as it was made for phone auth method, but I'm getting error:
[Error: [auth/notification-not-forwarded] If app delegate swizzling is disabled, remote notifications received by UIApplicationDelegate need to be forwarded to FIRAuth's canHandleNotificaton: method.]
Even though I followed the Appendix I'm still getting that error.
