How to external load-balancer?

Is there somewhere good information of how one would use a microk8s ha cluster with an external loadbalancer?

The only blogs etc. I find simply leave it at something like:
Use ingresses and then it is easy enough to configure an external loadbalancer.

I used Metal Load Balancer https://metallb.universe.tf/ for setting up a load balancer provider for my microk8s cluster. It was very easy.
