Charm stuck waiting with message "Ceph relation is missing data." when related to microceph

[MrClayPole]

When using microceph the ceph-csi appears to fail to configure itself correctly and shows the message "Ceph relation is missing data." while being stuck in a waiting state. I believe this is due to microceph running as a snap, and therefore, rather than ceph conf and keys being at /etc/ceph, they are stored at /var/snap/microceph/current/conf/. If I run "sudo cp /var/snap/microceph/current/conf/ceph.* /etc/ceph" on all nodes then this resolves the issue. Below is output from my "juju status" for reference

I also saw the following errors in the unit-ceph-csi-*.log
