Once you are happy with your template and want to set it live, you will need to choose who will use or see this template.
Inside the uiBuilder in the top right panel, click the settings button. This will reveal the template settings.
From here you can toggle the template status and you can also choose who will use this template. Enter the desired roles or username to the ‘Applies to’ option.
Here you can also add roles or users to the ‘Excludes’ option, this allows you to exclude users from the list it applies too. For example, you may want to apply a template to all Administrators except yourself, in which case you could type your username here.
Once you are happy with the setup, save the template and for the changes to then display you may have to refresh the page.
