DescribeTemplate
Use the DescribeTemplate operation to describe a template's
            metadata. To use this operation, you need the ID of the template that you want to
            describe. You can use the ListTemplates operation to list all templates and
            their corresponding template IDs.
Following is an example AWS CLI command for this operation.
The parameter value for alias-name can be $LATEST.
For more information about the DescribeTemplate operation, see DescribeTemplate in the Quick Sight API Reference.
