Salesforce OKTA iframe

We have Okta implemented for SSO for Salesforce. We want to implement an iframe that exposes an Angular application that we created. Since we have Okta implemented for SSO, I would think that we can also have the custom Angular application also utilize Okta for SSO. Is it possible to have access to the OKTA saml token within the salesforce iframe so that we can use it as a bearer token within our Angular app and use it to pass to our custom APIs?
