 */
export async function exampleRegisterButtonAndListener() {
 const ok = await PluginManager.registerButton(2, ['NOTE'], {
 id: 1,
 name: 'My Plugin',
 icon: '',
 editDataTypes: [0, 1, 2, 3, 4],
 showType: 1,
 });

 const sub = PluginManager.registerButtonListener({
 onButtonPress(event) {
 const { id, name, icon } = event;
 void id;
 void name;
 void icon;
 },
 } as any);

 sub.remove();
 return ok;
