How to modify third party app widget with code

[INKLY]

Hi I use this multifunction app called VITALS, and I would like to modify how it looks . Precisely I want to remove the amount of reviews showed next to the stars --> "(17 Avis)"  and put custom text instead. Does anyone know how to do this ? Thank you very much for your help !
