Web page access using Okta react native SDK


We have an app based on react-native and our organisation uses Okta for the SSO. I was able to use Okta SDK for authentication and MFA.
There is a specific requirement to open third-party websites that support our organisation and use the same SSO, using in-app browsers. The problem is that we cannot use access tokens to open restricted links on in-app browsers. Is there a way to use Okta SDK to achieve browser-like SSO authentication? The browser sign-in version erases the “sid” cookie of Okta which can be used session authentication, whereas if we attempt to fetch the access token using Postman, we get the session cookie and the access token too.
