Sigil superscript footnote size

Hi there. looking for a simple amendment. see screenshot. everything is fine. just want to reduce the size of the '3' of the footnote in the chapter heading to at least half the size. what tag/code do in insert before and after the '3' if this is possible?

thanks

David
