Answer 1

After a long struggle, I found the solution to update the AWS Cognito refresh token, To do this I am using the amazon-cognito-identity-js

const AmazonCognitoIdentity = require('amazon-cognito-identity-js');
const CognitoUserPool = AmazonCognitoIdentity.CognitoUserPool;

componentWillReceiveProps(nextProps) {
let getIdToken = localStorage.getItem('idToken');
    if(getIdToken !== null){
      let newDateTime = new Date().getTime()/1000;
      const newTime = Math.trunc(newDateTime);
      const splitToken = getIdToken.split(".");
      const decodeToken = atob(splitToken[1]);
      const tokenObj = JSON.parse(decodeToken);
      const newTimeMin = ((newTime) + (5 * 60)); //adding 5min faster from current time
      //console.log(newTimeMin, tokenObj.exp)
      if(newTimeMin > tokenObj.exp){
          this.tokenRefresh();
          console.log('token updated');
      }
    }
}

Updating the token method

tokenRefresh(){
    const poolData = {
      UserPoolId : // Your user pool id here,
      ClientId : // Your client id here
    };
    const userPool = new AmazonCognitoIdentity.CognitoUserPool(poolData);
    const cognitoUser = userPool.getCurrentUser();
    cognitoUser.getSession((err, session) =>{
      const refresh_token = session.getRefreshToken();
      cognitoUser.refreshSession(refresh_token, (refErr, refSession) => {
          if (refErr) {
              throw refErr;
          }
          else{
              //this provide new accessToken, IdToken, refreshToken
              // you can add you code here once you get new accessToken, IdToken, refreshToken
          }
      }); 
    })
}
