Refreshing an access token received from Google Identity Services / React App - reactjs

Question

I have a trouble right now with an access token received from Google Identity Services.
Some details about the case. I have full stack application, back-end based on Spring/Webflux/Hibernate-Reactive and frond end based on React. I'm using the google login feature from Google Identity Services with this react library #react-oauth/google.
I'm using the received "credential" after successful login for back-end access. Everything works like expected except that I there is no refresh token in the response after successful login. The token expires after 1 hour and a user must be prompted to login again to receive a new token, which is horrible!
So, how to refresh this token, any Idea?
I could not found more info on google side, that's why I am writing here.

Answer 1

So I found the solution by myself. I will post it here, in hoping to help someone else who is struggling with this problem.
So using the react library #react-oauth/google I used the useGoogleLogin hook. I added "flow: 'auth-code'" to function's options object.
const login = useGoogleLogin({
onSuccess: codeResponse => console.log(codeResponse),
flow: 'auth-code',
});
The function is triggered by click on simple button.
After successful login from the user, in the response object we can find a code property. We can exchange the code for an access,refresh and id token by calling the google oauth2 api:
curl --location --request POST 'https://oauth2.googleapis.com/token' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'client_id=your_client_id' \
--data-urlencode 'client_secret=your_client_secret' \
--data-urlencode 'code=recieved_code_after_login' \
--data-urlencode 'grant_type=authorization_code' \
--data-urlencode 'redirect_uri=one of your redirect uri's listed in your
credential'
after successful request access,refresh and id token are received.
refreshing the token also so simple:
curl --location --request POST 'https://oauth2.googleapis.com/token' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'client_id=your_client_id' \
--data-urlencode 'client_secret=your_client_secret' \
--data-urlencode 'grant_type=refresh_token' \
--data-urlencode 'refresh_token=received_refresh_token'
Here is the original Google documentation: https://developers.google.com/identity/protocols/oauth2/web-server#httprest_3
!important!
Remember that the refresh is valid until access is revoked. When you refresh the tokens, a new refresh token is not coming with the response. For further refreshes, you can use the same refresh token, receive by exchange.
