How to set formal or informal tone in DeepL Plugin

Hello

The DeepL web editor allows to set the tone as formal/informal. Nevertheless how can we do that through the DeepL Plugin in Studio?

I reached out to DeepL and they answered it's possible, nevertheless they won't tell me how, 'cause they say SDL is the one who developed the plugin so I need to ask them.

SO any clues guys? How can we define parameters of the Deepl Plugin for Studio?

Thanks!
