on book "done" or close event?

[FinalPlayer024]

How can I check if a player clicks "Done" on a specific book?

Spoiler: My code (if it can help you to "specific" what the book is)

command /book:
  trigger:
    set {_book} to a new book
    set {_titolo} to a new text component with "&7 Ok %executor%, sei entrato in &7modalità NICK! Per prima &7cosa seleziona un rank per il &7disguise."
  
    set {_testo2} to a new text component with "%last character of nl%%last character of nl%&b&lVIP"
    add hover event with action SHOW_TEXT with text "&7Avrai un nick &b&lVIP&7!" to text component {_testo2}
    add click event with action RUN_COMMAND with execute "/setnick VIP" to text component {_testo2}

    set {_testo3} to a new text component with "%last character of nl%&a&lVIP+"
    add hover event with action SHOW_TEXT with text "&7Avrai un nick &a&lVIP+&7!" to text component {_testo3}
    add click event with action RUN_COMMAND with execute "/setnick VIP+!" to text component {_testo3}

    set {_testo4} to a new text component with "%last character of nl%&6&lMVP"
    add hover event with action SHOW_TEXT with text "&7Avrai un nick &6&lMVP&7!" to text component {_testo4}
    add click event with action RUN_COMMAND with execute "/setnick MVP" to text component {_testo4}

    set {_testo5} to a new text component with "%last character of nl%&d&lMVP+"
    add hover event with action SHOW_TEXT with text "&7Avrai un nick &d&lMVP+&7!" to text component {_testo5}
    add click event with action RUN_COMMAND with execute "/setnick MVP" to text component {_testo5}
  
    add text component {_titolo} and {_testo2} and {_testo3} and {_testo4} and {_testo5} to book {_book}

    open book {_book}  to player

You can't tell when a player closes a book, only when they sign the book and when they edit within the book

Make the changes take action when they click a text component or make a confirm button.
