Unable to specfiy custom SecurityGroups for SingletonFunction

[joker3212]

Unable to supply security groups to the ECRDeployment construct to be used by the SingletonFunction. Currently the singleton function creates a default security group.

Would like to pass in a predefined security group like this

      ...
      memorySize: memoryLimit,
      vpc: props.vpc,
      vpcSubnets: props.vpcSubnets,
      securityGroups: props.securityGroups,
    });
