Do I need to install Swagger UI to use it with the NetQ API?

If you are using NetQ in an on-premises deployment, the Swagger UI is already built in. Just enter /swagger after the hostname or IP address you use to access the NetQ UI. For example, https://10.0.1.2/swagger

However if you are using a cloud deployment, you need to install the Swagger UI. See the NetQ userr guide for details.
