How to convert images to webp and download them from cloud server?

Question

Images

Hello! There is a site on wordpress with the installed plugin for saving images on the cloud server WP Offload Media .
Now I have a need to switch to using .wepb images in browsers where it is supported. To do this, I installed the WebP Express
plugin , which additionally converts images to the specified format. But, there are 2 questions of linking them together: 1) If you disable WP Offload Media and set the same settings , then everything works fine with the local folder, in this form the plugin gives

<picture>
    <source srcset="https://test.site/wp-content/uploads/2021/06/def_2.png.webp" type="image/webp">
    <img src="https://test.site/wp-content/uploads/2021/06/def_2.png" alt="" class="webpexpress-processed">
</picture>

But, if you enable WP Offload Media to load from the server, then it interrupts the html structure

<img src="https://test-wp.storage.googleapis.com/wp-content/uploads/2021/11/041343236/def_2.png" alt="">

How to make the structure be from WebP Expres and the link is taken from the WP Offload Media cloud ?
2) To send the .wepb format to the cloud , you need to connect the
as3cf_object_meta, as3cf_attachment_file_paths filters of the amazon-s3-and-cloudfront-tweaks add-on plugin , but this only works when loading new images in the media library, but what about those that WebP Expres converted , but they have already been loaded before?
