since you were in charge before, you must make it clear to the relevant person in charge before you leave. In the future, if you don't understand the handover, the other party may need to contact you. You need to be responsible for all this. If nothing else, you will find a new job. The new unit personnel will call the place where you used to work to investigate your past performance. If you don't make a good handover or cooperate well, the other party will say something bad about you casually.
