🚧 TODO

Some details:

• Similar to guests group mentions work with double quotes and specifying the type: @"group/admin"
• Suggestions for groups should be shown when autocompleting
  • They are returned on the mentions endpoint, identify by source=groups and should be shown with label and group icon in the dropdown list
• Group mentions should be rendered in the chat afterwards
  • They are like normal user and @all mentions just rich object parameters, this time with type user-group. We display them like all other mentions as a chip with a group icon as "avatar" (2 persons)
