Can you use XtraBackup to backup INNODB Cluster ?

Hi Guys, I have setup an INNODB cluster (Mysql 8.17) and was testing Xtrabackup (8.12) as a backup solution for the cluster. When I launch a backup, with the below command, this completes with the following error: 
xtrabackup: Error: Failed to find information for channel ‘group_replication_applier’ in SHOW SLAVE STATUS output.
Is anyone using Xtrabackup in this manner, or perhaps Xtrabackup cannot be used to backup INNODB Clusters?
Backup Command:
xtrabackup --defaults-file=/etc/mysql/my.cnf --backup --encrypt=AES256 --encrypt-key-file=/mysql_backups/encryption_key --extra-lsndir=/mysql_backups/2020-06-17 --compress --compress-threads=4 --login-path=mysql --stream=xbstream --parallel=4 --slave-info --use-memory=6G --no-version-check --target-dir=/mysql_backups/2020-06-17
