Cant enable Istio, btn is disabled


I am trying to enable Istio in an AKS Cluster, the docs says you should just enable it from the tools menu :

The thing is, the btn is disabled and its not possible to do anything in the interface.
I tried in an bare metal test env with an k3s cluster and the result was the same, I tried also diferent browsers, same result.

There is any pre-req that would disable the btn ? Should I add some required parameter in the interface that is not mentioned in the docs ?

Obs: There is no Pod sec configurated, and the nodes should have the required cpus, its an D2v3 AKS, my local cluster had 6x i7 core extreme cpus.
