Grok equivalent for the ZCML "require" directive

I am writing an add-view adapter and want to restrict its use to a specific resolution.

In ZCML, I can do the following:

<class class=".add.AddView">
    <require
        permission="cmf.AddPortalContent"
        interface="zope.publisher.interfaces.browser.IBrowserPage"
        />
</class>

      

        
        
        
      

    

Is there an equivalent way to do this?

Just using grok.require doesn't work.

My adapter looks like this:

class AddForm(grok.MultiAdapter, add.AddView):
    grok.adapts(IFolderish, IThemeSpecific, IDynamicViewTypeInformation)
    grok.name('addATDocument')
    grok.provides(IBrowserPage)
    grok.require('cmf.AddPortalContent')

      

        
        
        
      

    

But without the ZCML snippet, I can display the add view anonymously.
