Do we need a license?

Hello,

I developed a custom Adobe form via SFP transaction, on the form I placed a BUTTON UI and wrote a JavaScript piece of code that when user clicks this button a info message will be displayed on a popup and its a REGULAR type of button (not EXECUTE, not SUBMIT one), pl. let us know whether this form is considered as an INTERACTIVE FORM and needs license or just a PRINT FORM?

Regards
