Provider specific settings for Azure B2C

[esinmy]

I faced a few issues when setting up the configuration for Azure B2C, but it finally works.

The documentation has a section titled 'Provider-specific settings' which contains a configuration for Amazon Cognito. I would suggest adding the following for Azure B2C.

const mgr = new UserManager({
  // ...
  // automaticSilentRenew is turned off because redirect_uri is not passed to the signinSilent call inside SilentRenewService._tokenExpiring (oidc-client-ts.js)
  // If redirect_uri is not passed, it causes the error: "AADB2C90083: The request is missing required parameter: redirect_uri" during silent sign-in.
  // To handle automaticSilentRenew manually, userManager.events.addAccessTokenExpiring is set as shown below.
  automaticSilentRenew: false,
});

mgr.events.addAccessTokenExpiring(() => void userManager.signinSilent({redirect_uri}))
