Hi @hasibhassan, thanks for taking the time to submit a PR. This is not a typo. Here, "n" is used to indicate a placeholder for a number of policies. For example, in the IAM console, you might see this if you have more than 2 policies attached to an entity. We display Show 1 more text (or Show n more, for however many policies you might have). You can choose this text to expand the list to see all of the policies that are attached to an entity.
