Create a path to node/add in twig Can I use the path() function in twig to create a link to a non-node entity add form. Taking the group module as an example, if I want to create a link to the 'group/add' page in twig can I use something like:

{{ path('entity.group.add') }}


I know that the above does not work, neither does

{{ path('group.add') }}


Not sure if there is a way to do this with the various twig functions that create links.
According to According to Functions - In Twig Templates just Try 

{{ path('node.add', {'node_type' : 'yourcontenttypename'}) }}


as the example for article content type

{{ path('node.add', {'node_type' : 'article'}) }}


Update
Try 

{{ path('entity.group.add_form', {'group_type' : 'yourgrouptype' }) }}
