How to cancel sending an application from the site using events, CF7 plugin?

Question

WordPress

Often, users on a corporate site send several requests at a time. I want to make it so that 1 user can send 1 application, and the second one shows the message "You have already sent an application, expect a call."

There is an event on a click on the submit button for the CF7 plugin, in fact, through which I work.

document.addEventListener( 'wpcf7submit', function( event ) {
 if(event.detail.contactFormId=="32"){ // 32 это id формы для отслеживания
 alert("У формы №32 была нажата кнопка отправить");
 }
}, false );

But I do not understand how to cancel the sending of the message itself?

Answer 1

Instead As an option
alert("У формы №32 была нажата кнопка отправить");
event.target.querySelector('кнопка').remove()
