Stop input events, use custom ones, then restore the original?

This seems to work (in the emulator at least):

function removeListeners(events) {
      saved = {};
      events.forEach(event=>{
          let listeners = Bangle['#on'+event];
          if (!listeners) return;
          saved[event] = listeners;
          Bangle.removeAllListeners(event);
      });
      return saved;
}
function restoreListeners(saved) {
      for (const event in saved) {
          let listeners = saved[event];
          if (typeof listeners !== 'object') listeners = [listeners];
          listeners.forEach(listener => Bangle.on(event, listener));
          delete saved[event];
      }
}


// disable event listeners
const eventsToRemove = ['touch','swipe','drag','stroke','tap','­gesture','aiGesture'];
let saved = removeListeners(eventsToRemove);

// do Stuff

// when done:
restoreListeners(saved);
