HumanUI: File Picker clear location

I’ve read in the HumanUI threads before that there is a way to connect a HumanUI true/false button into the file picker that will reset the selected file or location…I have it working by connecting said button’s value listener to the “Must Exist” input on the File Picker component, but I get the SetComponent warning as expected…is there an alternative way to do this that doesn’t result in the Set warning?

does this answer your question?

I saw that, but can you provide a screenshot of how to connect the nodes properly for this arrangement? thanks!
