Hi There,
Thank you so much for getting in touch with us.
Unfortunately, this is not supported to translate the Categories and InfoWindows at the moment. We do apologize for the inconvenience.
With that said, we do have a experimental feature which we could try to use to translate the InfoWindows and Categories.
Please do let me know if you would be open to this experimental feature?
I hope this helps clarify, and I look forward to hearing back from you.
Kind Regards,
Abel
