The "Information for authors" claims that authors must provide the graphical abstracts for peer review while submitting.

While submitting to IEEE JSAC Special Issue, the author should submit their manuscript with EDAS as the call for paper instructions. But it seems that EDAS systems only accept the manuscripts in one PDF file while submitting.
What should I do to submit the graphical abstracts in this case?
I didn't find further information on this.
Thank you in advance!
