TablePaginationActionsProps is not overridable

Basically I've this interface from Material-UI docs while implementing CustomTablePaginationAction component Material-UI CustomTablePaginationAction

interface TablePaginationActionsProps {
  count: number;
  page: number;
  rowsPerPage: number;
  onChangePage: (event: React.MouseEvent<HTMLButtonElement>, newPage: number) => void;
}

The thing is if I want to add on this props interface like below

onChangePage: (event: React.MouseEvent<HTMLButtonElement> | React.ChangeEvent<unknown>, newPage: number) => void;

It gets me an error, like I can't modify/override the prop type.

Another question: why event object is a major param and needs to be passed all over? my codebase doesn't depend or need it.
