Cannot add second Google account (redirects to browser)

[kam1kaze]

When trying to add a second Google/Gmail account within the application, clicking the "Add account" button redirects me to an external web browser instead of handling the login process within the app. As a result, it is impossible to use multiple accounts.

To Reproduce:

1. Open Gemini Next Desktop.
2. Login with Google Account
3. Click on Profile Icon and then click "Add account".
4. See the redirection to the default system browser.

After logging in in the browser, the account does not appear in the desktop app.
