OAuth with facebook/gmail is not working on iOS simulator (Cordova app + Firebase) - ios

Question

I am trying to finish my last thing on cordova (+Firebase) mobile app and stuck with a problem.
So, I was working on social login for cordova app,
I was following this guide - Link to guide
when I've finished, I had some problems, but fixed them (only on android)
on iOS, when u click on some of login button - nothing happens,
BUT, when I hide the app (or just close it) and open it again, it start making redirect.
In that redirect I'm making login with facebook/gmail and then it redirects me to the link that I have in my config.xml
here is my request:
await firebase.auth().signInWithRedirect(provider);
const user = await firebase.auth().getRedirectResult();
, it works okay on android
and here is my config.xml (I've tried a lot of stuckoverflow and github solution there, so it can look messy
<?xml version='0.0.1.2' encoding='utf-8'?>
<widget id="com.appname.ios" version="0.0.1.2" xmlns="http://www.w3.org/ns/widgets">

Answer 1

Already fixed by doing next things:
On iOS social button was not even redirecting to appropriate provider because of some error that was stopping whole stack:
found answer here - fixedBugLink
After I've fixed that error, next things I was dealing with was that I could not return back to app after successful login
So I found that the problem was in unappropriate adding the next plugin -

I fixed problem with wrong URL scheme link, by changing the default one to
REVERSED_CLIENT_ID from GoogleService-Info.plist file in my iOS app.
So be careful with following guides (by the way I've followed this one - oauth-cordva-firebase
Hope this will help someone too :)
