Doesn't work with subresources?

[rehevkor5]

Expected behavior

When running a command to evaluate the access matrix of a subresource such as:

% kubectl access-matrix for pods/exec --namespace foo

I would expect it to print the access matrix for the pods/exec resource.

Actual behavior

It fails with an error complaining that it finds no matches:

% kubectl access-matrix for pods/exec --namespace foo
E0719 11:55:14.963247   45477 resource.go:80] determine requested resource: no matches for /, Resource=pods/exec

% kubectl access-matrix for pods/log --namespace foo
E0719 11:58:40.311999   46620 resource.go:80] determine requested resource: no matches for /, Resource=pods/log

Steps To Reproduce

See example commands above.

Context:

% kubectl access-matrix version  
v0.5.0
