Authorization error, the library sends request with using the client secret as bearer token instead of requesting a bearer token

[GerardPolloRebozado]

code:

import { Request, Response } from "express";
import igdb from "igdb-api-node";

const client = igdb(process.env.TWICH_CLIENT_ID, process.env.TWICH_CLIENT_SECRET);

export const getGame = async (req: Request, res: Response) => {
  try {
    const { id } = req.params;
    console.log(client)
    const game = await client.fields(['name', 'cover', 'summary', 'platforms', 'genres', 'release_dates', 'screenshots', 'videos', 'websites']).where(`id = ${id}`).request('/games');
    console.log(game.data);
    res.json(game.data);
  } catch (error) {
    console.log(error);
  }
}

error: data: { message: 'Authorization Failure.
