Not without setting up some wacky jquery that gets triggered somehow by something (some datachange) as a result of the microflow. But I would not go there, because your application will get less maintainable quickly.
You’ll want to call the second microflow in the microflow triggered by your button.
Or perhaps even better you can create a new microflow as a wrapper for the two.
If you’re trying to simulate two clicks you cannot do that via microflows as they’re executed server-side.
Hope this helps
