This is a very interesting map of the world, called the Endonym Map, and is self explanatory!! With the caveat that many countries have many languages, and so it’s the county’s official language (the website has more info, tho!).
And this one, called the Decolonial Atlas, is a very cool list of endonyms! Nice to have, considering an “official” language doesn’t necessarily mean that’s what’s most spoken/only spoken.
