Seeking Guidance on Connecting AWS Application Load Balancer (Account A) to ECS Fargate Cluster (Account B)

Hello all I'm currently facing a challenge and would appreciate some guidance on connecting an AWS Application Load Balancer (ALB) from Account A to an ECS Fargate Cluster in Account B. My objective is to efficiently forward traffic from the public load balancer in Account A to containers residing in a private subnet in Account B. If anyone has experience with such a setup or can provide insights into the necessary configurations and best practices, I'd be grateful for your assistance. I'm particularly interested in understanding the steps involved, potential pitfalls to watch out for, and any security considerations in this cross-account communication. Thank you in advance for your help!
