I really want to make the complete switch to DeepL instead of Google Translate, but I can't figure out how to setup the URL for auto detecting language.
With https://translate.google.com/?sl=auto&tl=en&text=SEARCHTERM whatever word or sentence I input, it uses the "Detect language" option, which I know that DeepL has as an option for too. But I can't figure out what keyword to put in the DeepL url, for it to use the Detect Language option.
Here's English to Spanish: https://www.deepl.com/en/translator#en/es/SEARCHTERM

Hopefully I'm just missing something obvious due to having been down with the flu this past week.
