How to access docker-machine instances that were created on AWS from new machine

I set-up some AWS EC2 instances using Docker using docker-machine on my previous laptop, using commands like this:

docker-machine create --driver amazonec2 --amazonec2-instance-type "t2.micro" --amazonec2-security-group MY_SECURITY_GROUP container-1

On the old laptop, I can still view and control them:

$ docker-machine ls
NAME                ACTIVE   DRIVER      STATE     URL                       SWARM   DOCKER     ERRORS
container-1   -        amazonec2   Stopped                                     Unknown    
container-2   -        amazonec2   Running   tcp://xx.xx.xx.xxx:yyyy           v20.10.7   
container-3   -        amazonec2   Stopped                                     Unknown

But on my new laptop, I'm not able to see them:

$ docker-machine ls
NAME                ACTIVE   DRIVER      STATE     URL                       SWARM   DOCKER     ERRORS

I have the AWS environment variables (key/secret) on the new laptop. I've looked at the hidden files in the old laptop to see if there's something that docker-machine uses to store a list of created containers, but I don't see anything.

Is there a command to add these to the new laptop, so I can see and start/stop them?
