Google tag conversion onclick button

Hi! I need to call a function onclick on a button.

Here is my code:

<div id="atendimento" class="tab_content">
                <?= $this->Form->create(null, [
                    'url' => ['plugin' => 'contacts', 'controller' => 'PropertyContactRequest', 'action' => 'add'],
                ]) ?>

And here is the form

Here the google isntructions:

In your html page, add the snippet and call gtag_report_conversion when someone clicks on the chosen link or button. -->

Just use some javascript embedded in the page, nothing to with cakephp here… its been a “while” since I did frontend dev, but something like:

document.getElementById("MySubmitButtonID").addEventListener('click', function ()

if you want something fancier like preventing double clicks firing 2 events you will need to make use of google.

Also worth mentioning is google tag manager - been years since i looked at it but I thought it was pretty awesome for this kind of thing at the time.
