using with oxygen builder theme

similar to this guy question https://www.ads-software.com/support/topic/webp-images-with-the-elementor-or-plugin/

I’m using oxygen builder and when I uses theme from Oxygen , webp is not automatically converted / bypassed.

I’ve tested this using your troubleshoot by enabling and disabling themes.
It works when I use normal wordpress themes.

I’m using Pass Thru option as my server doesn’t detect when I use htaccess.
Is there a solution to this other than disabling oxygen builder themes?
