Firebase account linking error

So when you try to login to an app using some other auth method, for example at first the user used Google and now he using FB and those 2 accounts have the same mail, you get that error

auth/email-already-exists

The thing is, that if you have 3+ auth methods, that error message isnt very specific and it could be a little tricky to develop a logic that handles this situation. How do you solve this issue?
