We've started using Clockify, a time tracking app, which integrates itself onto Trello cards via installation of the chrome extension. The result of this is a button being created under the "Actions" section of a card (see image below)

With the help of butler, I'm hoping to automate the triggering of this button whenever a member adds themselves to the card (i.e. the timer will start as soon as a member adds themselves to a card).
Is this possible? Or will automation only work with native "action" buttons?
I've browsed the help articles for Butler and done a couple searches in this community and on google, but haven't found anything.
Thanks for your help!
