long story short for the first time I got a Job Bypass FRP Google Account Redmi Note 9 where the Redmi Note 9 by the owner was intentionally HardReset but the owner did not know the risk of doing a hard reset which later required me to re-login the Google account using the last synced Google Account and apparently the owner doesn't remember the email and password at all. 
after I tried to find information via searching google, it turned out that to overcome the Android Redmi Note 9 which was locked in a Google Account, to overcome it, I could use the finger exercise method or manually without the need to use it it a computer or laptop.
if the Redmi Note 9 is already in the Account login preparation window position and cannot enter back into the initial Device setting setup window then we have to reset it so that the Redmi Note 9 can be accessed in the initial device setup position.
in the Connect to a network window, please connect your Redmi Note 9 with a Wifi network or you can also use an internet connection via a SIM card.

If the login and account sync setup process does not finish after waiting for tens of minutes or even almost an hour. Just execute the Redmi Note 9 with a hard reset using a key combination. Do a hard reset 2 times then automatically the synced google account will be deleted in its entirety and there is no need to re-bypass.
