How to click svg element within an iFrame using JavaScript or JQuery?

I am trying to use web automation and use JavaScript or JQuery to click the svg elements within an iFrame. I am trying to click on all the svg elements with class "expand-svg".

Here is the website: https://121fcu.org/careers/

Here is JQuery I tried using unsuccessfully:

var el = $("gnewtonIframe").contents().find("svg[class='expand-svg']");
el.trigger("click");

Here is JavaScript I tried using unsuccessfully:

document.querySelectorAll('svg[class="expand-svg"]')[0].click();

Any idea what I am doing wrong?
