Adding Custom JavaScript Button Trigger

Hi there! I'm trying to add the snippet below and paste it on an element that will trigger an application form.

klrRecruit.openRecruit()

The header snippet is installed:

<script async src="https://klear.com/dist/external.bundle.js?form=8d3eb1b3ab12a42d51d4a8807187db8a4c46a241"></script>

but I am not sure how to make the button open the form when it's click. When the code is inserted on the page—it automatically opens vs. opening when the button is clicked.

Can you share link to page where you use button? We can check easier
