EmojiOps to add watcher

[Mariena Quintanilla]

I was hoping to use emojiops to have people react if they want updates on a ticket.

That is, if they react with :eyes: they would get notifications on the ticket as it progresses.

Since I can't seem to add Watchers from JSM directly I was hoping I could at least access the user who triggered the rule and then a separate automation to add the watcher. 

Is this possible? {{initiator}} doesn't seem to be recognized when I try to set Approvers.

As a workaround I'm thinking to train people to comment in thread if they want to receive updates.
