Custom expiration time for custom auth token (within 1 hour limit by Firebase)

[cosmini]

I was wondering if it possible to create a custom token with a custom expiration for example just 10 minutes instead of default 1 hour.

In Kreait\Firebase\Auth::createCustomToken we can provide custom claims, but there's no parameter for expiration.

public function createCustomToken($uid, array $claims = []): Token

In Kreait\Firebase\Auth\CustomTokenViaGoogleIam::createCustomToken however, this is accepted as 3rd param

public function createCustomToken($uid, array $claims = [], ?\DateTimeInterface $expiresAt = null): Token

Can someone help explain if it possible and if not, why this is not an option?

Thanks 👍

This is now possible, with later versions of the SDK! 🙏
