I want to join VMs from another cloud to my cluster.(Flannel issue)

I want to join nodes belonging to networks different from Kubernetes to a cluster.
For example, two nodes are VMs from Kakao Cloud and the new node you want to join is a VM from GCP. The master node used kubeadm init using a public IP.

k get node -o wide       
NAME           STATUS   ROLES           AGE     VERSION   INTERNAL-IP    EXTERNAL-IP   OS-IMAGE             KERNEL-VERSION       CONTAINER-RUNTIME

node02         Ready    <none>          25m     v1.28.2   10.172.0.5     <none>        Ubuntu 20.04.6 LTS   5.15.0-1053-gcp      containerd://1.6.28

Although we succeeded in joining the VM in GCP, we confirmed that the kube-flannel in the VM in GCP was continuously generating errors and being regenerated.

k get pods -n kube-flannel -o wide

When I used the ip link on a VM in GCP, network interfaces such as flannel.1 and cni0 were not visible. How do I do this?

root@node02:/# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

       valid_lft forever preferred_lft forever
