Hello!!!
I am developing a project for Android, where there is authorization through Google.
After authorization through Google, I am given a token.

After authorization through Google, you are given a refresh_token and an access_token.
To get a new access_token, you need to make a POST request to https://www.googleapis.com/oauth2/v4/token
with the following fields
client_id = ;
client_secret=;
grant_type="refresh_token";
refresh_token=;
