I am lost using the MySQL Operator and InnoDBCluster CRD to configure a backup for the database. The backup is been loaded into the operator but data is never sent to the s3 bucket (in my case cloudflare R2).

I am confused what the configuration should be. From here there should be a secret
https://dev.mysql.com/doc/relnotes/mysql-operator/en/news-8-0-31-2.0.7.html

Here it referece to a config
https://dev.mysql.com/doc/mysql-operator/en/mysql-operator-properties.html#mysql-operator-spec-innodbclusterspecbackupprofilesindexdumpinstancestorages3
where no example for can be found.

manifest

Did someone alread managed to connect backup to s3?
Thank you
