```jinja hl_lines="7"

### Template Context Values

In the HTML that contains:

{% raw %}

			Type:        "string",
			Secret:      true,

		config.HelpKV{
			Key:         RolePolicy,
			Description: `Set the IAM access policies applicable to this client application and IDP e.g. "app-bucket-write,app-bucket-list"` + defaultHelpPostfix(RolePolicy),
