No, at the moment there is no option to update your status. After 4 minutes of inactivity you will be marked as away.

The different statuses are as follows:

  • Green circle: Online.
  • Orange circle (containing hands of a clock): Away.
  • No circle: Not online.
Note: the desktop app will keep you online if you're active on your computer (any click, keypress, tap) but the Web version can only detect activity in the browser tab.
