but i get this error : Behavior function in a non-behavior property. You can't use this property to change values elsewhere in the app

Behavior properties are the ones that start with On... like OnSelect or OnVisible. You need to put that function in one of those properties and use it to set a variable. Then you can add the variable where you are using it now to change the text. Since its a label I suspect you should put it in OnVisible for the screen or the label.

Use the following in the appropriate On... property.

Set(varTranslated,MicrosoftTranslatorV2.Translate("en","Bonjour"))

OnVisible may not be the right place to put it since that only fires when the screen is first loaded. It also doesn't work when you are in the preview in the editor. To test it I recommend putting it in the OnSelect property of a button. Then when you press the button you'll see the variable change.
