chrome.identity.getAuthToken({interactive: !!interactive}, function(token) {

Hi, in Brave Browser currently Version 1.3.115 Chromium: 80.0.3987.87 (Official Build) (64-bit)

I'm unable to login. Apparently, Google GAIA is not supported, the call chrome.identity.getAuthToken() returns the runtime error
Unchecked runtime.lastError: The user turned off browser signin.

Confirmed. GAIA is unavailable in Brave in any context."
brave/brave-browser#7693

Is there a possible solution or alternative or work-around to this issue in Brave please?

SOLVED: I have moved away from chrome.identity as it's not going to work with Brave, FireFox and possibly the new Edge when it comes out.

I have used as suggested elsewhere, firebase.auth().signInWithPopup() which will be cross browser friendly. Have it working in Chrome and Brave right now.
Reference page: https://firebase.google.com/docs/auth/web/google-signin

SUGGESTION: It maybe worth updating the example to either have a second example, or fall back to popup if chrome.identity is not supported.

Thank you
