Was not sure how to import my TLS certificates into AWS Certificate Manager.
The files you get from the download
First, click the SSL external link, if it's written "Have Certificate" in green.
The link will be like this: https://porkbun.com/account/ssl/MYDOMAIN.com
Then, download the SSL Bundle and open it.
Inside import certificate in AWS Certificate Manager.
For file -> Fill the input in aws:
private.key.pem
-> Certificate private key
First certificate block in domain.cert.pem
-> Certificate body
If intermediate.cert.pem
-> Certificate chain
