I have the exact other problem
I would like to search for 2 languages (one preferred), but and can’t work it out…
If you find a solution to your problem somewhere, please give the link/info as well, maybe it helps me…
I tried the trash guides ( https://trash-guides.info/ ), but it seems I’ve done something wrong. Maybe it helps you
This was the guide with the custom language:

Can I directly use the API myself?
