Description

The provided redirectURI in createNestablePublicClientApplication is ignored and the user gets redirected back to the current page.

Error Message

The redirect URI "brk-multihub://localhost:4200" is set in the auth config and in the returned controller instance from the createNestablePublicClientApplication function.

But the used acquireTokenSilent method from the controller instance ignores this configuration and sets, in the POST request, the redirect URI to the current page (brk-multihub://localhost:3000) instead.

MSAL Configuration

{
    auth: {
        clientId: "2a0bdc00-7caf-4f1d-a0a0-c7f48f3ddf2b",
        authority: "https://login.microsoftonline.com/organizations",
        redirectUri: "brk-multihub://localhost:4200",
    },
}

Relevant Code Snippets

const pca = await createNestablePublicClientApplication({
    auth: {
        clientId: "<APP_ID_OF_CDX_TENANT>",
        authority: "https://login.microsoftonline.com/organizations",
        redirectUri: "brk-multihub://localhost:4200",
    },
});

const tokenRequestPayload = {
    scopes: [
        "Application.Read.All",
        "MailboxSettings.Read",
        "Mail.ReadWrite",
        "Mail.Send",
     ],
};

await pca.acquireTokenSilent(tokenRequestPayload);

Reproduction Steps

1. Sideload a local test add-in in Outlook OWA
2. Execute the provided code snippet
3. Investigate the network tabs and compare the redirect URL provided in the request with the configured redirect URI

Expected Behavior

The acquireTokenSilent method from the controller instance should provide the configured redirect URI (in this case "brk-multihub://localhost:4200") in the request instead of the current URI (in this case "brk-multihub://localhost:3000").
