Hello,
Use the custom rclone authentication code like
@taranahalim937 mentioned.
When you get to the screen asking for select the account, don't choose the option "Use custom OAuth credentials". Instead, click on the "Get auth" button and enter with your own prefered google account.
Like it is showed on this video, shared by the tutflix team, via private message, when you first join the community

Note: Try not to copy too many files at the same time because of the rate limit error. In my case, some times even trying to do 1 by 1, i got the rate limit error.Trying again was enough for it to work
Hope it helps,
Cheers
