what is the difference between allege and accuse

Allege: It is used when someone does not have proof or any concrete base to assert the opinion. It is also used when one is a suspect in a crime but has not been proven as guilty Ex:- She alleged that the cafe uses stale milk in the coffee. Accuse: Here we are forcefully asserting something onto someone or something, whether it be true or not. It is also used when someone is charged with committing a crime based on reasonable proof Ex:- She accused the cafe of using stale milk in their coffees.
