Displaying language based on geo location is not accurate. Some regions have multiple official languages. For example, English and French are used in Canada.
Instead, we support displaying language based on a website visitors' browser language. You can set it in the "language selector" page in the App as shown in the screenshot below.
With this setting, if the website visitors' browser language is English, we will display your website in English by default to such visitors. If the website visitors' browser language is French, we will display you website in French by default.
