In docs i see instructions how to clone, but what about move cluster to another aws account in eks?
What i try?
Copy psql folder to the second account to already exist s3 bucket. Manually created secrets, use clone block with uid|cluster|timestamp. For now i getting error:

trying to bootstrap a new cluster
INFO: Running custom bootstrap script: envdir "/run/etc/wal-e.d/env-clone-test-postgresql" python3 /scripts/clone_with_wale.py --recovery-target-time="***"
INFO: Trying s3://****/15/ for clone

I see an issue which may help me. But i have question, is there any reason which may disserve to other psql clusters in second account? Do i need add CLONE_AWS_ROLE_ARN and CLONE_AWS_WEB_IDENTITY_TOKEN_FILE in postgres-operator configMap?
btw i already use in cm IRSA and don't understand why it not works with clone.
