It is designed to fetch and decode the authorization details stored on the blockchain. If the authorization details are not found or cannot be decoded, the function throws an error.
Throws

const authorizationUri = 'auth:cord:example_id';fetchAuthorizationFromChain(authorizationUri) .then(authorizationDetails => { console.log('Authorization Details:', authorizationDetails); }) .catch(error => { if (error instanceof SDKErrors.AuthorizationMissingError) { console.error('Authorization not found:', authorizationUri); } else { console.error('Error fetching authorization:', error); } });
