How to cancel a zle function after triggering the bindkey?

Hope you're doing well. I have the following in my .zshrc:

# 1. invoke zoxide to pick dir
# 2. open target dir in ranger
# 3. when exiting ranger, cd into last dir
zoxide_to_ranger () {
    eval 'ranger "$(zoxide query -i)" --choosedir=$HOME/.rangerdir < $TTY'
    LASTDIR=$(< ~/.rangerdir)
    cd "$LASTDIR" || exit

    # ensure precmds are run after cd
    local precmd
    for precmd in $precmd_functions; do
      $precmd
    done
    zle reset-prompt
}

zle -N zoxide_to_ranger
bindkey '^f' zoxide_to_ranger

As suggested in the inline comment, it's a handy tool such that when I trigger Ctrl-f, it'll prompt me a fzf menu, and upon selection it'll open ranger in that dir. The problem is that, when I want to cancel selection by pressing Esc, it'll still open up ranger and send me the home dir, which is not what I want. So my question is, how do I cancel such a zle function after triggering the bindkey? Config: zsh 5.9 (x86_64-pc-linux-gnu) OS: Manjaro Linux Any input is much appreciated. Thank you:)
