Portal and email component translations

[curiositry]

This is super hacky, but it seems to more or less work:

<a href="#!" class="gh-search" onclick="setTimeout(function(){document.getElementById('sodo-search-root').querySelector('iframe').contentWindow.document.querySelector('input').placeholder = 'Your placeholder text'},200)" data-ghost-search>Search</a>

I have asked about a better way to detect when sodo search is triggered over here:

Is there a way for themes to call a function when sodo search is activated?

I am trying to change the placeholder text in the search input with: document.getElementById("sodo-search-root").querySelector("iframe").contentWindow.document.querySelector("input").placeholder = "New placeholder text" … but as far as I can tell these elements don’t exist at the time of window.onload. Is there a built-in way to call a function when search is opened that I am missing — or should I add my own event listeners for when the search button is clicked / ctrl+k is pressed? Thanks!
