LanguageTool Premium and Doom Emacs?

Is there already a way (or a package) to call LanguageTool Premium endpoint to check the text I write in an Org buffer? The feature should be similar to this Obsidian plugin.

I checked flycheck-languagetool package, but it supports only the self-hosted version. I also checked languagetool; it does support calling the API endpoint, but I didn’t succeed in calling the endpoint, even when I already set languagetool-api-key and languagetool-username.

LanguageTool Console Command is empty.

I suppose I could spend some effort writing a package, but I want to ask if anyone has already had a solution first.
