Add a request header => accept-language: “” do work
like this

 'accept-language': ''

My request example

            await axios.get(`https://api.twitch.tv/helix/videos?game_id=${gameId}&first=5`,
                {
                    headers: {
                        Authorization: `Bearer ${accessToken}`,
                        "Client-Id": `${clientId}`,
                        'accept-language': ''
                    }
                });
