Best chin filler type & amount for a heart-shaped face? (Photos)

Looking to get chin filler to achieve a heart-shaped face, but can’t decide 1) what kind of filler to use (Juvederm Voluma, Restylane Defyne, etc.) and, 2) how many cc’s I will need (1 or 2) A nurse told me my chin projection is good but needs length. She recommended 1-2cc’s of Juvederm Voluma; however, I am seeing that Restylane Defyne might also be a good option? What type of and how much filler would be best to achieve a more v-shaped chin? Do I need more projection or length?
