@nikonhub thanks for the PR, looks awesome! I left one comment on one edge case.

[petar-cvit]

Not all rules will have apiGroups. With cluster roles, you can have a rule that has a nonResourceURLs field, and those rules will not have the apiGroups property.

You can create a Module from the Prometheus bitnami helm chart and you will get one such cluster role which has a single rule without apiGroups.

Because of that, the apiGroups here will be null and calling .map will break the UI

[nikonhub]

Yes right. I've fixed this case.

Should we display something for this rule ?

{
	"2": {
		"verbs": [
			"get"
		],
		"nonResourceURLs": [
			"/metrics"
		]
	}
}

It might be a bit confusing if you see a rule without any resources and just the verbs.
Can we conditionally add a column to this table? I was thinking of adding a nonResourceURLs column if there is at least one rule with the property. If not, I would leave those three columns. In that case, I would put the verbs as the first column, followed by APIGroups and resources and, if needed, nonREsourceURLs.

@nikonhub, can you check my comment above and add a column for nonResourceURLs if possible
