Is there a way to enable Okta Single Sign-On functionality in an Angular-based Excel add-in?

I have an Excel add-in developed using Angular, and I would like to implement Okta Single Sign-On (SSO) functionality to enable users to log in through the add-in. I have searched for relevant documentation but haven’t been successful in finding any.

Could you please provide support or guidance on how to achieve Okta SSO integration with an Excel add-in?

I am expecting something like this but implemented or integrated with Okta Enable single sign-on (SSO) in an Office Add-in
