That's a Pause Until action. I renamed it to make its purpose clearer. If you search for "pause" it will show up. Also, you can copy actions from one macro to another by selecting the action you want to copy, copying it, selecting an action or an empy action space in the destination macro, and pasting.
I wouldn't remake this from scratch because there are other parameters you have to adjust: in my macro's case you'd have to adjust the action timeout to something appropriate, as well as the "Reduce CPU Usage" setting (both accessible through the gear icon on the right) to X for the Pause Until action. The latter is a (poor) workaround to try making the Pause Until action work more reliably (see this thread for a more detailed explanation), in what is already a sort of clunky implementation.
This is probably an issue with Keyboard Maestro not detecting your mouse's clicks, which would mean it's an issue with either the trigger or the Pause Until action in my macro. I can't speak for Airy's macro. Can you try troubleshooting to try seeing if Keyboard Maestro detects your mouse clicks properly with this macro?

Just replace the trigger with your own mouse. This macro will display a notification every single time you press its trigger when Finder is frontmost.
Lastly, since you seem to have a Logitech G604, may I suggest you simply use any of its many many buttons as a trigger for a much simpler macro that consists of just the very last action ("Select "Enclosing Folder" in the Menu "Go" in Finder") in my original macro instead? This a more efficient approach in all respects, down to the number of clicks required (two becomes one).
