How do I recover a certificate previously issued?

I’m using Traefik with docker
A couple of hours ago I run into an unexpected rate limit issue with letsencrypt
Turns out I was generating a new request for certificate every time I restarted the development container!
Now, I need to publish my app this week, but with letsencrypt I can only ask for a new certificate next week
Is there any way I can recover my latest certificates and use those instead?
