Creating Datadog dashboards for separate AWS accounts with specific resources

Hi Team,
I have 3 AWS accounts with 1 datadog account, and i want create 3 datadog dashboards:
Dashboard1: to display AWS account A all resources (incloude EC2,RDS,S3…) But don’t show resources for B/C accounts
Dashboard2: to display AWS account B all resources (incloude EC2,RDS,S3…) But don’t show resources for A/C accounts
Dashboard3: to display AWS account C all resources (incloude EC2,RDS,S3…), But don’t show resources for A/B accounts
May I ask u what should i do?

Usually most customers would just make 1 dashboard of everything they want to see, and use template variables to dynamically choose whichever account they are interested in looking at in the moment

Thank you. That was very helpful
