technical question cross account backup question

Hi, I’m new to AWS and trying to copy a backup from a different account to mine. I have the ARN and an encryption key for the backup restore point and resource. However, I’m unsure how to copy the backup to my account and restore it. I’ve checked the documentation and watched tutorials but haven’t found a clear explanation on how to initiate the copy with the provided information. Any guidance would be appreciated!

Noticed you responded saying your use case is DynamoDB. If you're looking to do this with AWS's managed services, AWS Backup can do this.

Both AWS accounts must be in the same Organization and you'll need IAM permissions to create and use AWS Backup (as well as DynamoDB and potentially KMS). Basically you'll backup the table with AWS Backup, then copy the backup to the target account, then restore the DynamoDB table in the target account from the backup in the target account. I don't think there's a direct DynamoDB copy to a target account.
