* The configuration object for each tenant project keyed by tenant ID.
* The tenant name will be displayed on the sign-in buttons. uiConfig will
* be used to config FirebaseUI. You can specify the provider you'd like
* to enable for each tenant.
* You'll need to substitute the `TENANT_ID` with the tenant IDs of your
* project and `tenantName` with the display names you'd like to use for
* the tenant selection buttons.
* For SAML, OIDC and generic OAuth providers, you'll need to configure
* the `provider`, `providerName`, `buttonColor` and `iconUrl` in
* `signInOptions`.
