I need to grant access via AWS IAM SSO Inline policy (Permission set) to particular EC2 Instance alone

Question

I need to grant Full access via AWS IAM SSO Inline policy (Permission set) to particular EC2 Instance alone, the users should not be able to view other instances existing already, they can work on that particular instance alone only.

Tried this one but didn't get any forseeable results
