Xbcloud keys in Google Cloud VMs usage

MySQL & MariaDB Percona XtraBackup
1

Hi, We are planning to setup backup from Server to GCS bucket directly, we are trying to use xtrabackup and xbstream as streaming option. From documentation found the below:

$ xtrabackup --backup --stream=xbstream --extra-lsndir=/tmp --target-dir=/tmp |
xbcloud put --storage=google
–google-endpoint=storage.googleapis.com
–google-access-key=‘YOUR-ACCESSKEYID’
–google-secret-key=‘YOUR-SECRETACCESSKEY’
–google-bucket=‘mysql_backups’
–parallel=10
$(date -I)-full_backup

From the above, it is not clear about below two:

–google-access-key=‘YOUR-ACCESSKEYID’
–google-secret-key=‘YOUR-SECRETACCESSKEY’ \

are the above related to service account related keys? do we have to provide the path of the JSON or P12 keys someway?

and what is --google-secret-key specifically?
