DescribeTemplatePermissions
Use the DescribeTemplatePermissions operation to describe
                read and write permissions for a template. To use this operation, you need the ID of
                the template that you want to describe the permissions of. 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.
