Want to change H2 tag to H1 in epanel/featured slider

I am using the “TheCorporation” theme from ElegantThemes (https://www.elegantthemes.com/preview/TheCorporation/) which includes a large rotating image at the top of the page and some text. The text is currently specified as using the H2 tag and I want to change it to H1 instead. I’ve done searches through all the files in the theme’s epanel directory but haven’t seen where that is specced.

Any lead as to where to look to make this one character change would be appreciated. Thanks in advance!
