When i try to code the tutorials like on [Okta Auth JS and Angular | Okta Developer](https://developer.okta.com/code/angular/okta_angular_auth_js/) i always get the same error: error TS2416: Property ‘getValuesAfterProceed’ in type ‘EnrollPoll’ is not assignable to the same property in base type ‘Remediator’. Type ‘() =\> unknown’ is not assignable to type ‘() =\> RemediationValues’. Type ‘unknown’ is not assignable to type ‘RemediationValues’. 23 getValuesAfterProceed(): unknown; Seems like the tutorial is based on an old version of @okta/okta-auth-js. But when I do, like in the tutorial, “npm i @okta/okta-auth-js” I get the newest version. Why is this tutorial then for old versions? And how can i fix it? ---
