How do I use rysnc to copy my entire Google Drive to an external hard drive?

I am trying to copy my entire Google drive contents to an external hard drive.

1. I am using rsync with the built in Linux environment on my Chromebook.
2. I do not want to install a third party app on Linux. Also, I have Google advanced security turned on with a yubikey if that matters.

I first shared Google drive folder with Linux in the files app on my Chromebook.

Then shared my external using the files app on my Chromebook.

I then tried:

rsync -a /source/* /destination 

Seems to be working but multiple error messages. Seems like none of the Google Doc or Google Sheet files are copying over.

Should I instead use:

rsync -aH /source/* /destination 

Or this?

rsync -aL /source/* /destination`
