DeepL free API Key doesn't work

[CommanderN]

Hi, When I tired to enter Deepl Free APi I got this error mesage "Invalid API key. Please check the API key"
I tripple-checked the correctness of the key and it looks like this DeepL-Auth-Key {abXXXXXX-a1e9-4cc2-bbf2-fa67a1f0699b:fx} (I have deleted 6 charaters here, but thye are in the settings)
Does this tool works with DeepL free API key?
