Skill availability for a group of email addresses should not be case sensitive

When rolling out a new skill that we built in Creator Studio, we first test with a small group of people. This is easy when limiting access to a list of email addresses. Then we usually roll it out to a department that might be several hundred people and here is where it gets more difficult

• You have to use the, “Launch to the users matching the rule” and then put your users in a list like this: user.primary_email_address IN ["xx@xx.com","xx@xx.com”]
• Cool feature to have for adding 300 addresses at once, but did you know that the email addresses are case sensitive?

There is no reason to look at a list of email addresses where upper and lower case would be an issue. It is an annoying extra step to have to convert to lowercase every single time. Please fix this.
