Spellcheck underlines words in red :(

Good morning!

I use Zoom in Polish and I want to continue doing so. I use Windows 11 in Polish and I want to continue doing so. I temporarily changed language to English, in order to take a screenshot of my keyboard settings.

My problem is that Zoom has some sort of problem with words. I searched this issue online and found that it's usually a problem with Windows, not Zoom, but where exactly is the problem? In settings, yes but where exactly? I don't understand exactly what needs to be changed, so that Zoom and Windows understand that I don't want any word to be underlined in any language, no matter how correct or incorrect it may be in any language.

See 3 screenshots. Please could someone advise?

Thanks in advance!
