Rewrite the title as: Increase the validity period of Firebase SMS verification code

Question

Is there a way to extend the expiration time of Firebase SMS messages? It only seems to be valid for about a minute, sometimes it takes longer to receive text messages.

Update: I am sending the SMS via Web API.
