Can't add second interface to the pod with multus - minikube - kubernetes

Question

I am trying to deploy a pod with second interface using multus-cni. However, when I deploy my pod I only see just one interface the main one. The secondary interface is not created.
I followed the steps in the quick start guide to install multus.
Environment:
minikube v1.12.1 on Microsoft Windows 10 Enterprise
Kubernetes v1.18.3 on Docker 19.03.12
Multus version
--cni-version=0.3.1

Answer 1

I installed new minikube version, now adding secondary interface seems to be fine.
