How to change the WYSIWYG image domain?

when I choose a image from library, it will fill the default domain in it, how can I change this default domain? I try to update the interface options override and add three options in it but it still not work.

“relative_urls”: false,
“document_base_url”: “``https://xxxxxx/media/”``,
“remove_script_host”: false,

The image URL is added here: https://github.com/directus/directus/blob/073444ed33291895b0ed68ec3335f669319ec9c1/app/src/interfaces/input-rich-text-html/useMedia.ts#L172 It pulls in the current page URL when building the image URL so you may need to look at a Flow that would replace any instances of your directus domain with another domain name.
