* Handles the logout process for the user by revoking the token and redirecting.

* @param {Record<string, any>} req - The HTTP request object.
* @param {string|number} access_token - The access token of the user to be revoked.
* @param {Record<string, any>} cfg - Configuration object containing settings for the logout process.
* @param {boolean} existSession - A flag indicating whether a session exists.
*
* @returns {Promise<Record<string, any>>} Resolves with a result object or rejects with an error.
*
