What poliphili use for object-fit?

Good time of day.
Plz tell me, what poliphili uses to support IE11 in Edge and beautiful css properties - object-fit: cover (and his ilk).
Tried to connect to object-fit and object-fit-images, but I have not earned. Moreover, a demo exemple available in the repositories is also not working.
Am I doing something wrong? Or is there some solution?

In IE it works, in the Edge no (
