Get the name of the install plan from the subscription by running the following command:
$ oc -n external-dns-operator \
    get subscription external-dns-operator \
    --template='{{.status.installplan.name}}{{"\n"}}'
Verify that the status of the install plan is Complete by running the following command:
$ oc -n external-dns-operator \
    get ip <install_plan_name> \
    --template='{{.status.phase}}{{"\n"}}'

Hence, it needs to be changed.
Here is the updated look:
