kaddressbook group management

Hi there,

I want to use kaddressbook to manage my nextcloud contact groups. I did 
setup sync and can see all of my contacts and it is also possible to 
enter a group name in the search field and get all contacts in this 
group. My Questions:

- Is it possible to see a list of all groups?

- Is it possible to edit group membership of contacts?

- Did I miss something?

Regards,
