manually trigger lazy load for images iframe

Question

so I have an iframe where the images in the iframe are set to lazy load but the lazy load won’t trigger on small screens or some browsers.

<iframe src='https://opensea.io/collection/sorare?embed=true'
        width='100%'
        height='2500'
        frameborder='0'
        allowfullscreen>
</iframe>

is there a way to trigger the lazy load within the iframe on page load. maybe

("img.lazyload").trigger("appear");

or

lazyLoadInstance.update()
