Ignore cloudwatch group kms key warning

[abhi-vaidya]

I have code like below where I use ignore comment,
#tfsec:ignore:CKV_AWS_158
resource "aws_cloudwatch_log_group" "sfn" {
name = var.cloudwatchLogGroupName
retention_in_days = var.cloudwatchLogGroupRetentionInDays
tags = var.tags
}

I have tried with Rule AWS158 or aws-cloudwatch-log-group-customer-key too. But I see that tfsec isnt ignoring the rule. Please help
