How do I add a hook before exit?

[jackielii]

I'm trying to replace the floaterm with snacks.terminal. One important feature I use is the lf integration: https://github.com/jackielii/vim-floaterm/blob/master/autoload/floaterm/wrapper/lf.vim

IIUC, this wrapper injects a callback when the terminal leaves. Is there anything similar I can do in snacks.terminal?
