My custom tooltip wasn't displaying at all so I striped my document down to the bare bones and actually plucked an example from the bootstrap website. It still won't work.

Tried bunch of different examples and different ways of initializing to no avail. I need a tooltip to pop up.
The selector is running before the HTML is loaded, so no tooltip elements are found and initialized. If you run it after the window has loaded, it works:
<script>
window.addEventListener('load', function(){
const tooltipTriggerList = document.querySelectorAll('[data-bs-toggle="tooltip"]');
const tooltipList = [...tooltipTriggerList].map(tooltipTriggerEl => new bootstrap.Tooltip(tooltipTriggerEl));
})
</script>
Alternatively, you could move the block to the end of the document.
