No MSAL Node, você adquire tokens por meio do fluxo de código de autorização com PKCE (Proof Key for Code Exchange). O MSAL Node usa um cache de token na memória para ver se há contas de usuário no cache. Se houver, o objeto de conta pode ser passado para o acquireTokenSilent() método para recuperar um token de acesso em cache.
const msal = require("@azure/msal-node");

auth: {
clientId: "your_client_id_here",

Há várias maneiras de adquirir tokens em um aplicativo de desktop.
