I looked it up on SuiteAnswers and it says the only paramaters are options.id, options.label. But you pull it up on github and it shows interface AddFieldGroupOptions {
/** An internal ID for the field group. */
id: string;
/** The label for this field group. */
label: string;
/** The internal ID of the tab to add the field group to. By default, the field group is added to the main section of the form. */
tab?: string;
}
