Embedding dashboard language

Hello,

In the case of embedding, I want to customize the language of my dashboard based on the user's localization (data that I have).

Currently, I got a dashboard for each necessary language and I generate a URL based on the desired language. However, for the filters, there are elements that I cannot translate (cf image : FR dashboard but some texts are still in English).

After reading this topic: Embedding with Internationalization Support, I tried adding ?locale=FR at the end of the embedding URL, but I couldn't get it to work.

Does anyone have another solution?

Thank you for your help.
Regards.
