Conjur edge installation on AWS with multiple AWS accounts

Hello - If a customer has many AWS Accounts (Account) geographically separated in 4 regions, what are some of the best practices around edge installations ? I understand that the edge instances must be deployed closer to the workloads, so i get the region specific notion, but wanted to brainstorm this from an AWS accounts specific

  1. Should edge instances be installed specific to AWS accounts/regions ?, for e.g. if customer has 10 AWS accounts and 4 regions, then should we just install 8 edges for 4 regions (minimally required) or we need 40 edge instances ?

  2. If just 4 is needed, are there any challenges with cross account permissions ? for e.g. if a workload on AWS account 1 tries to retrieve secrets from edge installed on AWS account 2, assuming it’s on same region, will there be any concern ?

Thanks,
