error getting access token

Question

we are trying to call outlook mail send API behalf of third-party user after they allow permission to us

so for this first we get code by api

import { PublicClientApplication } from "@azure/msal-node";
const config = {
    auth: {
        clientId: "8bf2efb9-d262-4092-bfbd-1a2f05789277",
        redirectUri: "http://localhost:3000/setting",
        clientSecret: secreatID,
        authority: "https://login.microsoftonline.com/consumers", // Use the /consumers endpoint for personal Microsoft accounts
    },
};
const pca = new PublicClientApplication(config);

//GET AUTH-URL-CODE
export async function getAuthUrlCode(res) {
    const authCodeUrlParameters = {
        scopes: ["https://graph.microsoft.com/.default"],
        redirectUri: "http://localhost:3000/setting",
    };
    const authCodeUrl = await pca.getAuthCodeUrl(authCodeUrlParameters);
    return authCodeUrl
};

will get code on redirected URL

after that will try to get accessToken by...

export async function getToken() {
    const tokenRequest = {
        code: code,
        redirectUri: "http://localhost:3000/setting", // Must match the redirect URI configured in Azure AD app
        scopes: ["https://graph.microsoft.com/.default"],
        clientSecret: config.auth.clientSecret, // Include the client_secret parameter here
    };
    const response = await pca.acquireTokenByCode(tokenRequest);
    console.log('------', response.accessToken);
    return response.accessToken;
}

and will get error

    "status": 400,
    "message": "invalid_client: 70002 - [2023-10-16 09:45:07Z]: AADSTS70002: The provided request must include a 'client_secret' input parameter.\r\nTrace ID: 5854f7bd-b104-4796-995d-2fcd1af15801\r\nCorrelation ID: 59ec1fe6-9730-4b7e-a5e1-b053383639e8\r\nTimestamp: 2023-10-16 09:45:07Z - Correlation ID: 59ec1fe6-9730-4b7e-a5e1-b053383639e8 - Trace ID: 5854f7bd-b104-4796-995d-2fcd1af15801",

}
