3. Following sample shows how to initialize a Microsoft Graph SDK Client instance,

Using npm:

    import { PublicClientApplication, InteractionType, AccountInfo } from "@azure/msal-browser";

    import { AuthCodeMSALBrowserAuthenticationProvider, AuthCodeMSALBrowserAuthenticationProviderOptions } from "@microsoft/microsoft-graph-client/authProviders/authCodeMsalBrowser";
    import { Client } from "@microsoft/microsoft-graph-client";

    const options:AuthCodeMSALBrowserAuthenticationProviderOptions: {
        account: account, // the AccountInfo instance to acquire the token for.
        interactionType: InteractionType.PopUp , // msal-browser InteractionType
        scopes: ["user.read", "mail.send"] // example of the scopes to be passed
    }

    // Pass the PublicClientApplication instance from step 2 to create AuthCodeMSALBrowserAuthenticationProvider instance
    const authProvider: new AuthCodeMSALBrowserAuthenticationProvider(publicClientApplication, options),


    // Initialize the Graph client
    const graphClient = Client.initWithMiddleware({
        authprovider
    });

Using CDN or script:

const msalClient = new msal.PublicClientApplication(msalConfig);

const authProvider = new MSGraphAuthCodeMSALBrowserAuthProvider.AuthCodeMSALBrowserAuthenticationProvider(msalClient, {
	account, // the AccountInfo instance to acquire the token for
	scopes: ["user.read", "mail.send"],
	interactionType: msal.InteractionType.Popup,
});

// Initialize the Graph client
const graphClient = MicrosoftGraph.Client.initWithMiddleware({ authProvider });
