How do I reset the fields of XStream Out form when it closes?

Hello!

I call the XStream Out form using pipoDisplay(transStreamOutNewForm) command from my SKILL code. After that, I'm using a pre-generated template file using xstSetField("templateFile" <myTemplateFile>) command.

Next, I have 2 problems:
1) At the end of translation, I want to reset all the fields I have changed by performing an action equivalent to clicking on the "Reset All fields" button. However, I can't find any ways to do this from the SKILL code.
2) I don't know exactly when to use the "Reset All fields" function. SKILL provides only 3 time points when I can do this: when the translation starts, when it ends, or when I click on the "Cancel" button in the XStream Out form. However, I need the fields not to be reset at the end of the translation when clicking on the "Apply" button, but to be reset when the form automatically closed after clicking on the "Translate" button. In short, I want the fields to reset when the XStream Out form is closed, however, I cannot track this moment.

How can I reset all the fields of the XStream Out form when it is closed?
