Custom Presence or Callback method for Presence

Hi everyone,

I'm trying to build an app where I could listen for a change when the presence of current user is changed. For instance, when user switch from available to  busy, do not disturb, be right back or appear away. I can't find a method in microsoft/teams-js sdk. Is there a way to do it?

Also, I'm not sure if it is possible but is there a way where we could add a custom Presence separate from default Presence (available, busy, do not disturb, be right back and appear away)? then I can also add callback for this presence changed. It would be nice if this is possible. Please let me know.

Thank you.
